Where to Place Rear Rail of B and W Above Bed 5th Wheel Rail Kit 2021 Ram 2500

Published 10/12/2022

Question:

The instructions give a dimension from the back of the bed to the rear rail for a 6-6inch bed however my 2021 Ram 3500 short bed is a 6-4inch bed. Do I still use the 26-9/16inch dimension it shows in the instructions for the 66inch bed or is there another dimension I should use?

Yes, the correct rear rail edge to rear of truck bed dimension when installing the B and W Rail kit part # BWRVK2605 in your 2021 Ram 3500 is 26-9/16 inches like you mentioned. They got the dimension slightly off as they typically would just call it 6-1/2 foot length bed which is why the numbers aren't exact.
