Can an 80 inch couch fit into and be haul contained by a 2005 chevy trailblazer?
Answers: I have to agree with windowman, specially since you don't mention the height and width...could be like mad more hassle getting it in and out of the Trailblazer as opposed to a pick up.
it's not so much the length, but the height above sea level and width you need to verbs about. another concern is how far you plan on taking it and what kind of roads. if it is a strange couch and it doesn't cost too much to have it delivered, you may be better past its sell-by date, or check into renting a pick up or van from u-haul. (small truck is like 19.95 to 29.95)
