I just happened to notice that you and I have the same coach and engine (400 ISL). I am wondering about MPG on this size of coach and engine. I pull a 3500 pound Saturn Vue and I live in California, meaning no matter where I go I am rarely on flat road except up and down the San Joaquin valley. Depending on the average terrain I get between 6 and 7.5 mpg. Does that sound about right to you? Also, is there a "tunner" of any kind for this engine that's worth its salt? Gary (garyj@prodigy.net)
