Definately get a Bed Rug from Wise Industries. It's a zip together plastic carpet liner that velcroes in. I just put mine in, way better than a spray in cause it provides impact protection and things don't move an inch. I went camping, slept back there and it's nice and soft. Looks like a million bucks, fits like a glove. I know, sounds cheap, but you have to check it out. I paid like $350 with tax. Lifetime warranty. I almost made the mistake of spray in. Capped the rails with Bushwacker bed rail and tailgate caps painted to match the truck. Again, impact protection.
