I had thought from reading on this sight and asking a couple friends I would be getting around like 14 15 mpg. well im not Im getting like 11 pulling a 12' tandom with 2 mowers on it. what mods are the best to improve mpg. Owe ye blue book is $30,000 on it.
If the trailer is under about 5K pounds loaded, try towing with the Tow/Haul mode off. If I tow my ATV trailer(about 4K pounds loaded with ATV's) with the Tow/Haul mode on, I get around 10-12 MPG. If I turn it off, I get 14-16. The Tow/Haul mode is just too aggressive with the shifting for such light weights.
