Just an idea

Just was wondering if anyone knew if it was at all possible to take a 7 foot bed and replace a 6 foot bed on my supercab.

Sure if you feel like stretching the frame at the same time. Distance from the front of the box to the wheel arches is greater on the 7 foot bed.

You will need to some fab work to do it, but it can be done. The bumper will need to be moved back as you know for example. I don't know anybody who has done this before. I know people who cut the bed down to bob it and that looks sweet!!!

Ull need to extend the drive shaft also, because ull have to move the axle too.
Your truck is basically a long bed frame, but instead of using 1 feet larger bed, it has 1 feet larger cab.
