Thanks for the correction Franka. Even 8.33 @ 50 gallons is only 416.5 lbs. which I do not think is a fatal flaw in your coache's ability to drive or on your pocket book for increased fuel costs. I find it hard to believe that RV mfg's would install fuel, water and propane tanks on a coach that would make it a road hazard if all
were full? Add for most DP's a minimum of 500 lbs of tongue weight, plus the added weight of loading a coach for the road and....well you get the idea. What most of us owners are more concerned with is fuel economy and so the one/half full tank seems to be a good compromise, but not a requirement.
