I'm late to this discussion however my advice is that you should not be overly concerned with fuel mileage. If you have a diesel pusher just enjoy the adventure. Make sure you do regular maintenance including all filters and add some injector cleaner every few tanks of fuel. I just finished a 10,000+ mile trip to Alaska, got about 8mpg. But more importantly, the 55 day adventure cost me less than $150 per day, everything included (fuel, food, entertainment, activities). I never worried where I was going to sleep, eat or go to the bathroom. We stopped whenever we found a lake, river, mountain view or valley that we liked. Try doing that in a car that gets 30+ mpg. Enjoy the adventure, you are driving your personal one bedroom luxury apartment. If you don't believe me, figure out what you would pay for gas, lodging, meals and entertainment driving a car on a 55 day, 10,000 mile trip. Joe
