70 gallons tank.
Ford 6.8 liter V10.
31' coach with an average weight around 17,000 lbs.
Average city mileage maybe 6, freeway/highways high 7's. Bumper to bumper traffic I'm happy to see 5 m/gal. I'll loose about .5 m/gal from the averages when we take the 3000 lbs. toad along.
Dash fuel gauges are not always accurate. Half a tank remaining on the gauge with 250 miles behind you might not get you another 250 miles down the road. Know your coach before living on the edge.
Recent weekend outings close to home ran the tank down to a 1/4 of a 1/4. Filled up with 70.191 gallons consumed over 541 miles giving me 7.7 MPG. Flat roads around south eastern Virginia with a light load to sustain two people over two nights. No toad along for the ride.
Under reported my tank size in my original post. A 1/4 of a 1/4 with a 75 gallon tank left me with 9 3/4 per the dash gauge but actual volume remaining was about half of that.
