Default Re: OT: What type wood between frame rails and truck box?

I think this is being way overthought.This is going to be a shim between the body and frame,strength is not an issue.I installed a lot of bodies in the 80's,we used whatever hardwood was around.Mostly maple and ash.Most of the bodies I installed were running well over 100,000 miles a year in all conditions.The wood would hold up better than the U-bolts in the salt.I think wood is a good idea on a single frame truck.That frame has to flex,and wood allows it to do that without cracking things.If you go overboard on the U-bolts the wood has a little give.
