Was thinking of all you guys heading to Warwick.
There might be a few towing with vehicles running on LPG - and sometimes planning the trip between tanks can be a bit of a challenge.

This little baby takes the guesswork out. It tells you the distance between stations that stock LPG and so on.

Hope it helps.
