You should have the 115 gallon tank. Some 2005ís got the 100 gallon tank. Ours behaves similarly, much like the gauge in my pickup truck.
Iíd speculate that if you put 100 gallons in an empty 115 gallon tank, the gauge would show as full. If you have the 115 gallon tank and add 50 gallons at 3/4 then you have 65 in the tank at 3/4. Fuel cut off to the generator is at ~1/4 tank, so ~30 gallons. Figure 1 gal/hr at full load, 1/2 gal/hr at half load. If you park with a full tank the generator could run for 85-170 hours before fuel is cut off.
Iíve found that the coach can cover 500 miles on the first half of the tank, according to the gauge, and 300 miles on the second half, so I always try to fill up at 1/2, because the mileage is so much better.
That was attempted humor.
