As I said, I've only topped off once and you need to do that twice to more accurately reflect the "current" MPG. That said, when towing my 15ft enclosed trailer with 2 fully loaded touring Harleys and other gear (probably 4-5000lbs) pen and paper says about 7.5 AVG MPG. This was on 1500 mile trip from FL to MI last spring (we traded our old MH in down there).
A 500 mile round trip with the scanguage last October showed an AVG MPH of 7.9. Now this is without pulling that trailer. So, I would have to say it's pretty close at this point.
While I'm here and on this subject, SG says to stop filling up when the pump shuts off and to do that each time, which I did on my first fill-up. However, I can always get at least 7-8 more gals in there if I top it off. So I'm going to start over and top it off each time. This isn't going to effect the MPG calculations, but may effect my gals to empty. I'll say that because I have a 75 gal tank punched in, but I have to no clue when topped off if I actually have 72 gals available or 85. I really don't care about that anyway. I'll know a lot more when I get to FL next week. I'm also going to level the coach each time while I'm dialing everything in.
I have a Ford 2 valve 6.8L V10.
