Joking aside.I have run 6 x 25L barrels and a trolley from a Honda estate.Then I put a 175L in the far back of it sideways on so that it rested over the one third part of the back seat and against the front passenger seat. The reel and battery and pump sat next to the tank.Then I got a Doblo Van with a 400LThen when I went two man I added a trailer with a 200L as well.Now I have a Hyundai iload with a 650L.The best? Either the Doblo with 400. (1 man) or the iload with 650. (1/2 man)If I really really really couldn't afford a van I'd buy a 2/H trailer with a 400kg payload and stick a 250L on board and insulate it.
Slippy, if you are that hell bent on serious injury mate, just jump off a bloody high bridge. It's less hastle all round for you.
