It's a Trucker Movie through the Nuclear Wasteland - Damnation Alley

Some guys go for a ride in a motorhome. And that's about it. It's one of the poorest executed movies 20th Century Fox ever put out. The movie consists of 1) blow up world 2) blow up only safe place 3) drive to Albany 4) get a bump on the head and die, get eaten by cockroaches, get raped by mutant rednecks, pick up a junior sized Peyton Manning, float motorhome from Detroit to Albany 5) Profit?
