What speed where you traveling? Your average MPH is really good for that many miles. You must have stayed in the driver seat pretty straight. I always have to stop every 1 1/2 to 2 hours for wife to go tinkle. Anytime you have to keep stopping it really cuts into average MPH. When I'm out in our little Miata I can do much better MPH but I go a lot faster in it than in the truck towing.
