We rent this every year in northern spain for 4 weeks. A bit less than $100/night.
Last two years it was the french pyrenees. This year we are trying for the alp maritime and piedmont. Totally self contained so we sleep for free up in the mountains.
Diesel motor and heater/hot water heater, solar, inverter, full kitchen and room for bicycles in the back. Not sure why these european layouts are not sold in the usa. Its a rebranded 22 ft promaster but narrow enough to squeak through little mountain towns.
