Don't overlook the little Romahome. I love my Citroen based one, but if I was on a budget I'd have one of the early demountables based on a Honda Acty. You can drive the van out from under it and then you have a little pickup. 
Surprisingly quite a lot of room inside, and when the original van wears out, you can just drop another one under it.
