DH and I are seriously considering this. We have two young children and we've just been on a short break for half term and we've been inspired. Dh is ploughing full steam ahead into looking at vans to buy and I'm being a little more cautious. How cost effective is it to have your own accommodation as oppose to hiring a static caravan? Do you use it as much as you planned or intended? Are there any 'must have' features? Where is the furthest you've travelled? Also, if you don't mind answering, how much did it cost to convert?
