Where are you located?
I am in Arizona and may decide to sell my very simple but very affordable Dodge penthouse top SMB van. I use the pop top when up for gear storage so there is no mattress for the top....it would be too narrow up there for two adults anyway.
It is an auto with the small V-8 (good gas mileage), has about 80,000 miles, regular wheelbase, small 2 way refer, electric two burner stove or one burner butane portable, small 10 gal water tank, elec h2o pump and small sink, grey water tank, side cabinets with countertop, forward facing couch bed that folds into bed with lots of storage underneath, and porta potti, no furnace, no shower, or roof a/c but does have aux shore power ac.
This is a very simple, lightweight, low mileage van, with new HD tires, has been recently inspected and okayed by my mechanic. I would have to sell it for about $8,800...... But that is a heck of a lot cheaper than the $30-60 fully equipped rigs. With some minor interior custom work done by you to meet your own needs, it would be a great, cheap way to have a daily driver that is also good for three season camping.
This easily fits in my carport with a 7 foot entry height.
I was going to gut it and redo the interior to my special needs, but like many well intentioned guys, just have not gotten around to it. This summer I will be moving back up to the mountains in the northwest, and since I have a newer big ass 4wd pickup, I will probably instead just build a camper for that.
Let me know if you are interested enough in this unit
to make me get off of my lazy butt and take and send some pics!
