lpg conversion

who out there has put lpg in there trucks? want to put lpg on my 80 1fz-fe. 4.5l inline 6 what gear did you use? what did it cost? did you go dule or only lpg??? any help out there spending way to much on petrol 1/4 of my wages go in the tank for like 200km a week and lpg way cheeper at the pump

Considering lpg conversion for my 96 prado, anyone recomend some in Braintree, Essex area or has used the large companyin wales that turn vehicle round in a day, sales blurb gives impressive guarantees in writing but always wary without a recomendation!!
