Wow, $165,000 for an extremely unattractive "house truck" that lacks the equipment and amenities of a nice "regular" camper... amazing. For that price I'd at least expect a nice set of polished wheels, not the stock grey painted steelies! I'd pay $10 just to learn if it ever sells.
If you have huge money to spend on a camper, look at the EarthRoamer. It's $250,000 to $600,000 but at least it's really awesome!!
I also must take exception to the builder's statements that a trailer cannot be taken down an unimproved road or backed out.
