Parts Needed to Flat Tow a 2012 GMC Sierra 3500HD 4WD

Question:

I have a 2012 GMC Sierra 3500HD 4wd truck. I need a 10,000 lb hitch like this Roadmaster. Can you tell me which base plate will work with my truck? Also, is there a description of work needed to attach base plate to truck. Thanks!

For a base plate kit for your 2012 GMC Sierra 3500HD 4WD truck I would recommend the Roadmaster XL Base Plate Kit # 3167-1, I will send you a separate email with a pdf of the installation instructions for this product for you to check out.

This base plate kit would work well with the RoadMaster Blackhawk 2 All Terrain Tow Bar # RM-422 that you referenced.

To complete your towing setup you will also need safety cables, # BX88197 and a lighting kit such as # RM-2120.

And finally, most states now require a supplemental braking system on the vehicle being towed. The easiest to install and use is the Roadmaster Even Brake portable proportional braking system, part # RM-9400. This unit activates the brakes on the vehicle being towed in proportion to how much the RV is braking. This is the safest type of braking action, and it reduces wear and tear on the RV and towed vehicle brakes. I attached an FAQ on supplemental braking for you to check out also.

You will also want to check the vehicle owners manual for additional information on flat towing the vehicle. Some vehicles require an axle disconnect, drive line disconnect, transmission lube pump, or free wheeling hubs in order to be flat towed.

I also attached a couple FAQ articles on flat towing that you might find informative.
