If I won the lotto I might setup a b double with a Volvo tug. A trailer is living and b is for the critters, DMax and camper. Then we wouldn't need a house sitter if we want to go away!
How sad is that? I've already put our's on the drawing board, but a V8 Scania instead (just to stand out from the crowd

). Living quarters in the A, garage in the B. But awfully hard to fit a 4wd, camper and tinny in the B and keep it under 19m overall length for general access, non B double routes. Be slightly better off with a rigid truck and pig trailer, but that wouldn't be as cool as saying you had a BD motor home

Yes very sad how much thought I have put into it, considering the lotto win would be the only way to pay for it
