Question:

Hi, I just bought a 2021 double cab Toyota Tundra. I inherited a Reese pro series hitch and rails. I need a installation kit for the rails. Id prefer something thats alittle more dummie proof as this is my first time installing something like this and have no idea what I need. Thank you

Assuming that the bed rails you have are from Reese, you'd need the # RP50084 frame brackets. (You want to ensure that the frame brackets and bed rails are from the same manufacturer). You'd also want to go with the # RP58504 bolt kit to fasten the bed rails to the frame brackets. The existing hardware for your bed rails isn't meant to be torqued multiple times, so it's recommended that new hardware be used.

Also, keep in mind that unless your truck has the 8 foot bed, you likely won't have proper clearance between the front of the 5th wheel and the back of the truck cab for turns. For 6-1/2 foot beds, be sure you're using a slider hitch. For the shorter bed, you'll want to make sure the 5th wheel is equipped with a rotating pin box like the Reese Revolution or Sidewinder. I'll link to a help article that explain how these work.

If you want to install a 7-way connector in the truck bed so you don't need to run the trailer connector cable up over the tailgate, you can install one using part # 41157.

I've linked to installation instructions for the bracket kit as well as to an install video for the trailer connector harness mentioned above.
