In reply to Dick Barton, an old VW is more than adequate for camping and biking. The thing you have to remember is that you don't buy a 1960's/ early 70's vehicle to expect it to perform like a vehicle 40 years younger.
Part of the charm is being outside of the run of the mill rat race, that demands you get to wherever it is you're going as fast as you can. You break the journey up, and enjoy the scenery along the way.
We've just returned from a 2 week adventure in the Lakes with our bikes (which we also got married in the middle of :D) and my camper performed faultlessly for the entire time! 8)
