In my old gas motorhome I was in the slow lane with that V10 screaming going over the Sierra's. In the diesel Super C, I'm in the passing lane. You will never make up the fuel cost vs the extra cost of the diesel. Gas was 6 mpg, diesel is 9 mpg going with the flow of traffic or 11-12 mpg going at V10 speed. The driving experience is much better with the diesel especially if you tow.
