I'm going to see my buddy that runs a propane company this weekend so I'll ask him for the "official" word, but in the meantime here's what I know.

They run Ford trucks in their service fleet, and for a while they were buying the factory conversion. Since then they have switched to a different company, and rather than pulling the heads and replacing valves and seats before operation they just run them until they need replacing and then do it. Most of their trucks run a half million miles before the vehicle itself is used up.

One thing they do on all of their propane conversion vehicles is start on gasoline. Easier to light, especially in cold temperatures ... like when you might need a generator most. See if any of the conversion kits allow you to retain some gasoline aspect.

Like I said, I'll see him this weekend and pick his brain. In the meantime, stay warm and well lit.
