my ?400 camper was road worthly, it had a years MOT but no one wanted it cause of what it looked like, it was just very very rusty but the places that were important were fine. It had gone on teh roof at teh back, bottom of all teh doors etc... it was umm light blue with red patches lol and it had a big name accross the roof back Bertha Bus.
I sold it for ?650 a few weeks ago and am pleased to say that the new owner took it to vanfest and she made it there and back with no trouble.
Even at the ?650 price we had over 100 calls, I think it is best to find a cheap one that already has a MOT so you no teh main stuff is done and then the rest is possible but down to you to do it in yoru own time.
We got some very funny looks, people laughed at it and most people didn't beleive that it had a MOT
