Oh nice one mate, from what I've heard there is a good saving for long distance driving. Tlag know far more than me about LPG I'd say he was one of the 1st to get onto LPG when it came out here from what he's said before in the past :D Not saying you are old Tlag. Just a head of your time ;)
And I've seen the inside of a few vets cars and they are all a mess so can understand from that point of view :D
