At most the 2017 GMC Canyon will have a curb weight of 4,545 pounds for the 7,500 pound capacity of your Class C RV is more than enough.

The truck can be towed with 4 wheels on the ground only if it is a 4x4. If you have a 2-wheel drive model it will have to be put on a tow dolly and towed with the front wheels on the ground and the rear wheels on the dolly. For more information check the owner's manual starting on page 354.

Roadmaster has base plates confirmed to fit the 2017 GMC Canyon, # RM-523182-4, as long as the vehicle does NOT have adaptive cruise control. For a compatible tow bar I recommend the Falcon 2 # RM-520 rated for 6,000 pounds. For safety cables I recommend # RM-643. The coiled design helps keep the cables off of the ground.

For lighting a simple magnetic kit such as # RM-2120 is a good option because it bypasses the vehicle wiring and it is easy to set up.

You may also need a high/low adapter to keep the tow bar level. I have linked a help article showing how to measure and a link to the high/low adapters we carry.

And finally, most states now require supplemental braking on the vehicle being flat towed. One of the preferred systems for our installers and what I recommend is the SMI Stay-IN-Play DUO proportional system, # SM99251. It will apply the vehicle brakes in proportion to how much the tow vehicle is braking. This is the safest way to stop and it reduces wear and tear on both vehicles.

The # RM-88400 relay is required to prevent the towed vehicle's brake signal from overriding the turn signal from the RV when applying the brakes during a turn. The RM-88400 relay is not required when using magnetic tow lights

Be sure to consult your vehicle owners manual for specific information on flat towing the vehicle. I have also included some helpful links to our series of help articles on flat towing for you.
