Duel Fuel Class A

Many years ago, many of the fleet vehicles we'd use were converted to run on propane. The conversions never worked well. They had noticeably less power, were hard to impossible to start in colder weather without starting on gas and converting once warmed up. Of course the tanks were huge as well taking up half the bed of the truck. For a RV where pulling power is always in need I would think they would be a poor choice.

Again, the trucks I'm discussing were gasoline converted to propane. Had they been designed from the ground up to run on propane the outcome may have been different.
