Seems like motorhome mfg's can't decide either. We're about 50/50 for gallons/lbs looking at other brochures.
Just an FYI, according to my numbers its approximately a 50#(WC) tank. We have 9.8 gallons of usable propane (41.356 lbs assuming 4.22 lbs per gallon). 9.8 is 80% of the actual tank size (9.8/0.8 = 12.25 gallons or 51.695 lbs). If we're splitting hairs.
