Be sure to follow these guidelines to prevent possible hazards from misuse.

Important Safety Check List

1.

 Do NOT exceed the trailer’s maximum weight capacity load of 1,000 lbs (455 kilos)  The Gross Vehicle Weight 

Rating (G.V.W.R.) for the GearWagon™ 125 trailer is 1,480 lbs (672 kilos), and is calculated as follows:

The Empty Weight of the Trailer (480 lbs/218 kilos) + the maximum payload the trailer can carry (1,000 lbs/455 

kilos) = 1,480 lbs/672 Kilograms G.V.W.R.

2. Make sure the towing vehicle as well as the hitch is capable of towing the trailer and its payload. Check your vehicle 

and hitch owner’s manual for tow ratings.

3. The tail light bulbs supplied with this trailer are for a 12 volt DC electrical system only. Do not attempt to power the light 

bulbs with any other type or voltage electrical current.

4. Always check to make sure the payload being transported is properly and safely secured in the trailer. Never place-

loads on one side only. Load the trailer evenly from side to side with 60% of the load forward of the axle (the tongue 

  weight is 10% of the load, which does not include the wieght of the trailer. The load is divided so that 90% of the load
    is over the axle and 10% is over the tongue). See diagrams below:

Before Each Use 

Trailers are generally not used everyday. Your trailer may sit for extended periods of time between uses making it very impor-

tant to check all components thoroughly before each use. Following these simple instructions will maximize the life of your 

trailer and keep you safely transporting your cargo.

  Always check wheel lug nuts for proper tightness. When using trailer for the first time, check wheel lug nuts for 

proper tightness at 50 miles of travel. Before every subsequent use and at 500 mile intervals during every trip, check 

and tighten the tire lug nuts. Always ensure wheel bolts are tight. Torque to 50 – 75 ft.-lbs.

  Inspect the general condition of the trailer. Check for loose bolts and nuts, misalignment or binding of moving parts, 

cracked, bent, or broken parts, excessively worn safety cable, damaged tail lights/side running lights/wire harness, 

loose lug nuts, loose hitch connection, and any other condition that may affect its safe operation.

  Check your maintenance schedule to ensure that all routine maintenance matters are current. Perform any neglect-

ed maintenance by a qualified technician. 

  Check the tires for wear and the tire pressure for proper inflation (30 PSI).

  Check the operation of all lights. Replace any faulty bulbs. Operating lights are mandatory on a trailer. Periodically 

check lighting when towing over long distances. Check the tightness of all connections.

  Make sure wiring is properly installed and secured to trailer to prevent from hanging and catching on any road debris.

  Make sure the safety cables are attached to the trailer and the towing vehicle. Criss-cross cables as necessary to 

prevent from hanging and catching on any road debris.

  Check and adjust your tow vehicle’s tow height to make sure that the trailer is being towed level.

  Check that the trailer coupler is fastened securely onto the trailer ball. The GearWagon™ 125 is equipped with a 

2” coupler and must be used with a 2” trailer ball. After assembly and attachment, pull up and down on the coupler 

to make sure the hitch ball is fitting snugly in the coupler. If the coupler is not secured properly, the ball could come 

loose while the trailer is in motion, possibly causing property damage, serious personal injury, or death.

•  Verify that endgate is secured by properly closing draw latch.
•  Verify that the lid is secured using elastomer draw latch and pin locks furnished.

WARNINGS

Failure to adhere to these recommendations may result in potential hazards from improper operation, includ-

ing property damage and bodily injury. 

  Keep children away.

 Be sure children are kept a safe distance from the trailer operating area.

  Never sit, stand, or ride on the trailer (people or pets).

 Serious injury or death could occur.

  Whenever possible, park the trailer on a flat, level, paved surface and chock both tires to keep the 

trailer from accidently moving.

  When driving do not exceed the speed limit.

 Braking time can be considerably longer when a ve-

hicle is towing a loaded trailer. Excess speed is a major cause of vehicle-trailer accidents.

  Make sure the coupler is secured properly to the hitch ball.

 If not secured properly, the ball could 

come loose while the trailer is in motion, possibly causing property damage, SERIOUS PERSONAL 

INJURY, or DEATH.

  Tighten wheel lug nuts.

 Failure to properly tighten wheel lug nuts and to check for proper tightness 

during travel my result in property damage or serious personal injury.

• 

Secure lids 

using elastomer draw latches and pin locks furnished.

• 

DO NOT EXCEED YOUR VEHICLE’S TOW LIMITS OR TRAILER’S LOAD LIMIT. 

Refer to your 

vehicle’s towing information to learn the capabilities and limits of your vehicle.  Refer to GearWagon 

125’s weight specifications on page 3 for load details.

Coupler

Make Sure That the Trailer Ball is Completely 

Engaged in the Coupler Ball

Place coupler over the 2” trailer ball on your vehicle. Raise the 

locking lever to allow the coupler to drop fully onto the hitch ball. 

Press the locking lever down on the coupler to make sure the 

hitch ball is fitting snugly in the coupler. There should be no play 

between the hitch ball and the coupler. If there is play, tighten the 

adjustment nut until no play is present. If the adjustment nut is too 

tight, the handle will not lock. 
To adjust coupler to ball, raise the locking lever, push up on the 

channel lock and turn nut to tighten or loosen the coupler. Proper 

adjustment is obtained when coupler is as tight as possible on 

the ball and locking lever can still be opened and closed.

GearWagon 125’s coupler comes with the Handi-Grip handle and Stabilizer swing arm stand with caster for easy maneuver-

ability when uncoupled from the vehicle. The Stabilizer swing arm secures in reclined position for transit.  Pull arm away to 

release from notched position in order to operate in downward position for trailer support. To adjust swing arm height, simply 

adjust arm length by pressing the release latch on the arm.

Hitch, Ball, Wire Plug

GearWagon 125’s can be pulled with any tow rated vehicle and receiver (Class I on up).  Never exceed your vehicle’s tow 

limit, as specified by your vehicle and hitch manufacturer’s rating.  See page 3 for trailer weight and load ratings.

The optimal ball height is 17 inches from the ground. Coupling the trailer at the 

designed height will insure that the trailer floor is level in orientation to the ground.

The GearWagon 125’s coupler fits a 2” size ball. Make sure that the ball used is 

matching in size and is rated equal to or greater than the towing load.

GearWagon 125 uses a four-flat connector plug. Vehicles with a round pin plug should source a wire plug adaptor.

Lid and Endgate Operation

Opening and Closing

Use the lid handle for opening and closing tonneau style lid.  

Release the gas shock by pressing in when closing lid 

(GearWagon 125 Camper model). Rotate draw latches 

inside trailer to open and close endgate. The endgate 

may fold to the ground by releasing the cable carabiners.

Endgate Weight Rating

The endgate supports 400 lbs of weight for sitting.  It is not designed

for load bearing weight as a ramp. For heavy wheel items like ATVs, a ramp should be used.

Securing Trailer for Transit

For security, two Locks with a sets of keys are included. To apply locks, first 

close Lid and secure Lid Latch. Remove lock from pin and insert pin through 

hole located at the lip where lid and base overlays.  Apply Lock by inserting into

 pin 

(we recommend applying lock above the lid as shown in photo). 

At a notched location, turn key counter clockwise to lock; turn key clockwise to 

unlock. 

Be sure that lock is engaged 

after removing key

 (pull on lock). 

Weight and Load Ratings

The Gross Vehicle Weight Rating (G.V.W.R.) for the GearWagon™ 125 trailer is 1,480 lbs (672 kilos), and is calculated 

as follows:

The Empty Weight of the Trailer (480 lbs/218 kilos) + the maximum payload the trailer can carry (1,000 lbs/455 kilos) 

=1,480 lbs/672 Kilograms G.V.W.R.

WARNING

Lock down lids using either one or both pin locks 

before transit. Failure to do so may result in property 

damage under extreme road or weather conditions.

SolarVENT

Integrated in the GearWagon 125 Camping Trailer is the SolarVent, a solar powered ventilator for removing 

condensation from accumulating during the night. While moving 1,000 cubic feet per hour, it will run for up to 48 

hours without sunlight and prevents mold and mildews.

To operate, raise the vent fan and set to intake or exhaust.  When driving in rain, be sure to close vent to prevent 

water from entering.

Two AA  batteries are included. If the vent is not working, the batteries may be dead and need replacement. To

Bearing Inspection / Replacement

GearWagon 125’s axle bearings have been factory lubricated.

 The bearings should be inspected any time the hub 

is removed from the axle or at intervals as outlined in the maintenance schedule shown on page 11 of this manual. The 

bearing cones should show no signs of excessive wear or damage such as flat spots on the rollers, broken cages, pitting, 

or corrosion. The bearing cups that are pressed into the hub should also be checked for wear or damage. If the bearings 

do need to be replaced, follow the procedure as outlined and only use bearings that are approved for use in the following 

chart.

IMPORTANT:

 

Both the bearing cup and bearing cone should be replaced any time a bearing is replaced.

The following procedure should be used for bearing cup replacement:

1. Carefully tap the existing bearing cup out of the hub using a brass punch
2. Clean the bore area after removing the cup to ensure there are no nicks or burrs.
3. Carefully tap the new bearing cup into the hub making sure the cup is seated against the bottom of the bore.

 Inspection, Maintenance, and Cleaning

All replacement parts, maintenance and repairs should be undertaken by certified and licensed technicians. The buyer 

assumes all risk and liability arising out of his or her repairs to the original product or replacement parts, or arising out of 

his or her installation of replacement parts.

  Once a year or every 6,000 miles, inspect the bearings for proper lubrication. Repack if necessary. Be sure to 

have a qualified technician re-pack the hub assembly and handle other maintenance items.

  To reduce friction between the coupler and hitch ball, apply a layer of heavy weight grease over the hitch ball. 

Lubrication of the coupler should be done periodically to stop corrosion and keep parts moving freely.

  When servicing, use only identical replacement parts. Only use accessories intended for use with this product. 

  Any modifications made to the trailer or parts of the trailer will void the trailer warranty and release Let’s Go Aero 

of any responsibility for damages, injuries, or accidents incurred.

Wiring

 The GearWagon™ 125 has a four flat-connector wire style plug. This is a common pin hole configuration for the 

wiring of towables. Check to verify your vehicle’s wiring plug style. Should it differ, consult your local hitch installer 

for a wire plug adaptor.

 Always check all lights before towing for brake, running, signal, and side marker light operation. Make sure that all 

your connections are solid and that all wiring is in good condition. Should the brake, signal, or running lights not be 

working, first check that the vehicle’s lighting is operating properly. 

Note:

  Bare, striped or pinched wire will cause a short in the trailer, which will cause the vehicle fuse to blow. A solid 

ground is required for your lights to work properly. All contacts must be to bare metal. Light covers should be 

well maintained and kept clean. Be sure that your lights are always visible, not obstructed by your load.

To test vehicle wiring:

You will need a 12v light tester. Attach the wire clamp of the tester to the ground wire on the vehicle plug. Then 

touch the tester pin into one of the vehicle plug contacts. Turn on the corresponding vehicle operation, i.e., run-

ning lights. This will illuminate the tester light if the vehicle wiring is correct. Follow this same procedure for the 

signal and brake lights.

Bearing Lubrication

GearWagon 125’s axle bearings have been factory lubricated.  For continued maintanance, below is a listing of 

approved lubrication:

The GearWagon trailer’s axle is equipped with the Sure Lube 

greasing system which allows, the bearings to be lubricated without 

the hassle of packing the bearings by hand. After assembling the 

unit, simply apply grease through the grease fitting that is in the 

end of the grease cap or spindle. The grease used should meet the 

requirements as shown in the chart above. The following amounts 

of grease should be used:

 5-7 ounces to completely exchange the grease throughout 

the hub

 1 1/2 - 3 ounces every 12 months or 6,000 miles thereafter or 

as use requires (ie, if submerged in water).

With the Sure Lube System the grease is pumped through the 

hub via the grease zerk located in the end of the grease cap. The 

grease is forced through the bearings and out of the exit hole ahead 

of the seal. The old grease that is inside of the hub is forced out of 

the hub cavity and exits though the rear hole on the spindle. You 

can visibly tell when the old grease is flushed out when you see a 

steady flow of the new grease coming from the rear of the spindle 

(with exception to the straight style of axles). The grease can then 

be wiped from the rear of the spindle or, in the case of a straight 

axle, the grease will flow inside of the axle tube.

Bearing Adjustment and Hub Installation

Bearing adjustment is a very important part of achieving maximum bearing life and trouble-free service. Most bearing fail-

ures can be attributed to improper bearing adjustment, normally due to the bearings being adjusted too tight.
Once all of the necessary inspections have been performed and the units have been properly lubricated, the following 

procedure should be used for reinstallation of the hubs:

1.  Place the lubricated unit onto the same spindle from which it was removed. Make sure all of the components are 

reinstalled as they were removed.

2.  Tighten the spindle nut to 30-40 ft./lbs. while turning the hub to ensure the bearings are properly seated. Do not 

move the hub after this step is completed.

3.  Loosen the spindle nut completely until the nut can be turned with your fingers.

4.  Finger-tighten the spindle nut by hand without moving the hub.

5.  If the cotter pin can be assembled with the nut finger-tight, insert the cotter pin without backing the nut off. If the cot

-

ter pin cannot be assembled with the nut finger-tight, back the spindle nut up to the next available slot and insert the 

cotter pin.

6.  Bend the legs of the cotter pin over the top of the spindle to ensure the spindle nut will not back off.

7.  The spindle nut should be free to move with your fingers with only the cotter pin holding it in place and the hub 

should not have noticeable movement when pulled back and forth.

Rubber Torsion Axle Suspension

Except for periodic inspection of the fasteners used to attach the Rubber Torsion axle to the trailer frame and a visual 

inspection of the welds, no other suspension maintenance is required. However, all maintenance regarding hubs, drums, 

rotors, bearing, wheels, and tires, should be adhered to.

The Rubber Torsion Suspension System is a self-contained 

suspension system that is housed entirely inside the axle beam. 

Unlike the spring suspension system, the axle beam attaches 

directly to the trailer frame without the need for various mount-

ing components. The action provided by the Rubber Torsion 

Suspension System is unique from the leaf spring suspension 

providing several operating advantages including independent 

suspension and a virtually maintenance-free suspension system.

How the Rubber Torsion Suspension System Works

Rubber Torsion Axles provide a much improved trailer 

ride relative to conventional spring axles through a 

unique arrangement of the steel torsion bar surrounded 

by four natural rubber cords encased in the main struc-

tural member of the axle beam. The wheel/hub spindle is 

attached to a lever, called the torsion arm assembly. This 

assembly includes the torsion arm, the torsion bar and 

spindle. As load is applied to the trailer, the torsion arm 

assembly pivots around the torsion bar, causing a rolling 

or compressive resistance in the rubber cords inside of 

the axle beam. Both sides of the axle are completely 

independent from one another.

Direction of Travel

Rubber Torsion axle beams and stub axles must be 

mounted with the torsion arm and spindle trailing to the 

rear of the axle beam.

As Load is Applied to the Trailer, the Torsion 

Arm Moves to Absorb the Shock

Direction of Travel

Trailer

Wheels and Tires

Wheel Selection

Wheels are a critical component of your running gear system. When specifying or replacing your trailer wheels it is 

important that the wheels, tires, and axle are properly matched. The following characteristics are extremely important 

and should be thoroughly checked when replacement wheels are considered.
1. 

Bolt Circle.

 Many bolt circle dimensions are available and some vary by so little that it might be possible to attach 

an improper wheel that does not match the hub. Be sure to match you wheel to the hub.

2. 

Capacity.

 Make sure that the wheels have enough load carrying capacity and pressure rating to match the maxi-

mum load of the tire and trailer.

3. 

Offset.

 This refers to the relationship of the centerline of the tire to the hub face of the axle. Care should be taken 

to match any replacement wheel with the same offset wheel as originally equipped. Failure to match offset can 

result in reducing the load carrying capacity of your axle.

Torque Requirements

It is extremely important to apply and maintain proper wheel mounting torque on your trailer axle. Torque wrenches 

are the best method to ensure the proper amount of torque is being applied to a fastener.

It is important that the specified torque levels are maintained on the wheel nuts or bolts on your axle to prevent loose 

wheels, broken wheel studs, and possible wheel separation from the axle.
Wheel nuts and bolts are offered in different cone angles (usually 60° or 90°). It is important to match the angle of the 

fastener to the wheel on the axle.

Tires

Like the tires on a car, the most important factor in the life of the tires on your trailer is their inflation pressure. Check your 

tire placard for the amount of pressure for the specific capacity of your trailer. Inflate to 30 psi for GearWagon. During use 

of your trailer, inflation pressure should be checked weekly and performed when the tires are cold (prior to operation of the 

trailer). In doing this, you will ensure that you are achieving the maximum life and tread wear for your tires.

Wheels and Tires – Inspection and Maintenance

Wheels should be visually checked periodically for dents or cracks. Whenever it is required to have a tire replaced on a 

rim, the wheel needs to be checked for balance and distortion.
Tire wear should also be checked often for abnormal or excessive wear. The following chart will aid you in troubleshooting 

if abnormal or excessive tire wear should occur. It is important to monitor tire wear, as once a wear pattern becomes firmly 

established in a tire it is difficult to stop, even if the underlying cause is corrected.

2. The tightening of the fasteners should be done in stages. Following the    

 

 

 

 

recommended sequence above, tighten fasteners per the wheel torque    

 

 

 

 

chart below.

3. Wheel fasteners should be torqued before the first initial road usage and    

 

 

 

 

after each wheel removal. Check and retorque the wheel fasteners after the first 50 miles and again at 500 mile 

intervals. Check periodically thereafter to ensure that the proper torque values are maintained.
