I have the seats out of my 2-door and use a Harbor Freight 40x50inch moving blanket. It fits perfect, costs $4 and provides reasonable padding/protection from dog hair, etc. They're super light weight, so when it gets all nasty or ripped or whatever, I just replace it with another.I see many of you have, for lack of a better term, blanket type things that go from the back of the front seats to the tailgate. Anyone mind sharing what they are? I have a dopic 1yr old English Mastiff, and he's about to be a Jeep dog!
