after lots of research, phone calls, emails, etc., i decided to get a EZ-Dump Insert for my truck. i was wondering if anyone ever had the bottom and sides of their dump beds lined w/ spray on bedliner? all of my trucks have always had Rhinoliner brand and i love it, but i havent seen it on any dump beds before. i cant actually think of any disadvantages for it either as most of the dump inserts or dump beds i see that are 2+yrs old, are starting to rust out already.
