first where you are and are going can you buy propane, propane is a great fuel if it is available burns cleaner and the minor power loss is not generally a problem.
it costs less per gallon engine life is much better drive ability if set up properly is just as good as fuel injection.
the bad is you have to maintain it, the heat exchanger will need rebuilt every few years and the coolant level in the radiator is very important, it will freeze up if you run low on coolant even though the rig isn't running hot.
but i have gathered up a dual fuel system for my four wheel drive which i hope to install this summer my reason is the truck sets a lot and propane doesn't go bad in the tank like modern gasoline. so i am a fan of propane
if it fits into your lifestyle yes it is a good deal if not run the other way
