Ours will take almost exactly 2.5 gallons to fill at that point so I've surmised that ours is 10 gallons. I suspect it has more to do with the chassis builder than the motor home brand. In our case, we're riding on a Spartan. __________________ *Jay and Peggy Monroe* "Can't take it with you, not leaving any behind" 2024 Jayco White Hawk 26FK 2024 Ford Expedition
