similar to Marty...just a landlord who uses the truck as a truck...not every day, but often enough to understand both those who use their 'truck' more as a 'car'...
Both do a good enough job for the majority of the Rv.net/forum crowd...all the way to Marty's full time 'work' crowd...
My drop in has been there since somewhere in the 80's. Has a 1/4" thick sheet of 'green' plywood, glued to the sheetmetal bed bottom. It is also molded to fit 'underneath' the pickup bed's top rail and it also has fasteners that clip underneath the pickup bed top rails. So it will NOT float off out on the highway and also have a cap (which is taken off for 'work'...dirt/gravel/cobble stones/bricks/firewood/etc)
Nephew & neighbor both have CTD 2500HD and around the corner guy has a F350 SuperDuty. All have sprayed on (one factory, other two drop in). They sometimes help with my properties and I help with their properties hauling dirt/gravel/etc.
All four are holding up, with mine the oldest. NONE of ours has had it scraped/dented/etc down past it to the sheetmetal.
Locally, have heard of a couple who found the bad apple applier...think they are there in every locality. Just the luck of the draw and up to the buyer to check them out
IMHO, they are all good and just go out and find the best deal out there.
