[The Gritz Carlton]

Outside of the initial trip home from the dealer when new (400 miles), I've never run with all tanks empty. I always keep fresh water tank completely full. After dry camping, that water (along with waste) is now in the holding tanks but still onboard. After 4 days at the drag races, I took coach to dump station and emptied all tanks. I then go home, refill FW tank, clean her up and stow her away. I was amazed at the difference in performance when running with all tanks empty!! It's about 700-800 pounds less weight. I've never had a real issue with reserve power but what a difference!! I'll rethink this issue of keeping fresh water tank full all the time except when I know we are heading out for boondocking! It makes me wonder if I might increase fuel mileage a bit. Maybe I need to chew my food a bit longer too!
