I'd go for it. 3 bills isn't that much if the drivetrain's as good as stated.I have a friend who can usually do a cab swap in about a day,from drive it in to drive it home,if things don't go seriously sour in the process. Or,like was suggested,flip it for a profit...I might be interested in the hoist works for my ol' Mack.
