My husband and I are about to (possibly) order a new 36' Hitchhiker Discover America, but we want to use some of our own furniture rather than what traditionally comes with it. The only problem is, we can't seem to find a way to get something like our sofa-sleeper or our queen-size mattress into the thing through that skinny front door! Is there another avenue we can use to get the furniture inside, or do we have to hire someone to pull off one of the slides?!?
