Might be a little small for what you want Ali, But look at Vauxhall Combo vans! My dads buisness has 2, there non stop 9-5. The main work horse has done 190k and is a 53 reg! Only thing that its needed is a new se of filters and tyres every 30kish. It's an absolute beast. If you go to auctions, you can pick up an ex royal mail van cheap, and they have all the gadgets and gizmo's, Twin side loading doors, electric wondows all round, cd/radio, aircon. Quite cheap too! Both of them we have are 1.9tdi's and do about 50 mpg, and then the astra van we have does about 60, but thats not as much of a whale. Models with the back seats that fold, are eassily big enough to sleep 3. I've kipped in ours before with the missus when I've been camping and it was to foul to put the tent up. Plent of room, fold the seat down and an air bed fits perfect, Not a dedicated camper then! Quite like a crsa to drive, 'cept a looooad more body roll etc, but what can you expect, its a van
