Recommended Parts to Flat Tow a 2015 Chevrolet Silverado 2500 HD Duramax


I will be towing a 2015 Chevrolet 2500 heavy duty duramax diesel truck.. What wiring harness will be compatible with this truck? It is equipped with dual batteries.. I wil also be installing a braking system inside the truck.. I will also be purchasing a tow bar from you..

Out of the wiring kits available for your 2015 Chevrolet 2500 HD I recommend the # RM-15267. The kit includes a 6-way connector that will be installed at the front of the truck. Then there's an 8 foot cord that connects the 6-way and a 7-way on the back of your RV. It also includes the diodes and wiring to install on the Chevy.

I recommend the Exali-Bar II tow bar, part # DM9511013 with base plate kit # DM9517321. This way they'll connect right up to each other and you won't have to fool with any adapters.

For a supplemental braking system the Stay-IN-Play DUO # SM99251 is a favorite around here because of how reliable it is and it's easier to install than many other permanently installed systems. It's a permanent install so you won't have to mess with it once it's in the truck. You'll also need the Stop Light Switch # RM-751463 with it.

Finally, you'll likely need a high-low adapter. I've attached an article to help you determine the correct rise or drop your setup requires. I've also linked our selection of adapters for you to look at once you know what you need.

In addition to my recommendations I've linked some articles on flat towing that you may find helpful. You should also check your truck's owner's manual for any special instructions to flat tow it. Look for a section labeled "Flat Towing" or "Recreational Towing" or something along those lines.
