Wagoneer V8, 5,000'-8,000' avg elevation, driving is uphill from here in most directions, reduced power was very clear, about 20%

I live in the Sierras so driving is uphill for me too. I'm running Omni-Pak ignition, so that could be why I'm not seeing a power loss. I installed the propane conversion when gas went over three bucks a gallon. Propane saves me over a buck per gallon.

I never did run out of fuel, but was dismayed to learn that many fuel stations would not sell to me as they were not licensed to sell propane as motor fuel.

I've had that problem too. I generally run on propane for trips to town and back. For longer trips I run on gas to save the hassle of trying to find a propane station.
