i went propane with my last ride. it was great, we have forklifts at work and i would just swipe out tanks. don't put it under your truck and buy a back up at your house. alsooo get the adapter for the bbq gril tank. i've had to get propane from home depo and wali world in a pinch. other then not really having a fuel gage and finding places to fill its a great idea. ( if you role your engine will not shut off so you might want to think about a kill switch. )
