The least MPG that I recorded with any one of the three V10 that I had {still have one} was 6 1/2. Most of the time between 7 to 9 towing a 34 ft TT.
Exact same numbers for me, wether pulling a 30' trailer or my former 41' weekend warrior (probably helped the WW had a nice curved front cap). And that includes Oregon hills. That can mean 7% climbs for miles.
There are no number of miles where the fuel economy savings on a 6.0 would ever pay for the upgrades required to make it acceptably reliable to me, once the extra fuel cost (around here) is factored in.
