There isn’t normally that much dead space though. I think it’s a pretty cool idea, but how wide is the usable portion of your bed now? 4 feet or so?
Will it fit a sheet of plywood, 4 wheeler or a lawn tractor?
Again, really cool idea but it’s too permanent IMHO. You basically have to keep a bunch of shit in them or they are useless…or you drink a lot and always have cold beer on hand, lol
