Parts Needed to Flat Tow 2009 GMC Sierra 1500 Behind Motorhome

For a larger truck your 2009 GMC Sierra the Demco Exali-Bar tow bar # DM9511013 would be the tow bar that would work best. It has a 10,500 lb capacity and has longer arms which helps with turning range. For a base plate kit the part # DM9518200 is a confirmed fit for your 1500 and would work well.

For lighting you can use the diode kit, # RM-15267, and not have to worry about cutting into the taillight housing. This will splice into your taillight wiring to allow your tow vehicle to control the taillight assemblies of the towed vehicle. This comes with a round 6-way connector that you will install on the front of your towed vehicle and enough coiled wire to go from there to the RV.

And finally, most states now require supplemental braking in the vehicle being flat towed. An easy system to set up and use is the Blue Ox Patriot # BLU37TR, that applies 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.

Most likely you will also need a high low adapter so that the tow bar will be level when you are flat towing. I attached a link to a page that has all of the ones we carry.

I have included a couple of helpful links to our articles on flat towing for you. Be sure to consult the vehicle owners manual for more specific information on flat towing your vehicle. It's also pretty hard to come up with a budget friendly way to flat tow something as the parts are all pretty expensive and the cheap components really don't work well.

Thanks for the reply. If I decide to change toad to a 2001 Chev HD 2500 ext . cab 4 wheel drive diesel would components be the same?

You'd have to go with a new base plate kit like the part # DM9517101 but everything else can also easily fit the 2001 Chevy Silverado 2500HD 4WD as well.
