Those things are $Priceless$
They are great. The last modern generation of those (watercooled) are a little better suited to towing, though.
Had the Eurovan camper for awhile. Had some odd problems but was good for it's intent.Like an RV once you got it set-up you probably weren't going anywhere, unlike an RV you had to switch modes from sleeping to cooking/standing and there wasn't much storage space, but you could park it anywhere you can park a normal fullsize vehicle. They aren't cheap though. Got a 28' RV for 1/2 what it cost, when I sold it.
