gotpropane is saying the use 4 to 5 gallons propane for 8 hours of trail use with a stock 22r. now how much gas would you use in a gasoline rig doing the same? i think i use more than that even in 2wd on the road. i wonder how much run time they're talking about? any idea's? gas here is now regular $4.05 and propane $ 2.98.
