Nice, congratulations. Your towing mpg might increase some, but probably not much. I'm getting a coupe of extra mpg towing my 5th wheel. But my everyday driving is about 3 - 4 mpg better. And highway, empty, is even better still. I've gotten close to 23mpg on my two trips between Houston and San Antonio.
But the real improvement will be that engine. It is a true pleasure to pull my 5th wheel with the new engine. What I've said before, and what others have said will hold true. The first time you pull with it, you'll see what we're talking about.
Keep us informed as you get it and hook up the first time.
