We had an Autosleeper Trident (high top VW T4 conversion) for 10 years. Flippin' excellent vehicle, we took it all over the place, including France and Spain.
We bought it in 1998 for £18,000 and sold it in 2007 with 120k miles on the clock for £10,000 so they hold their value really well.
Here it is in the Pyrenees:
