I tow about 12k# FW with a 5.9 Cummins. Get about 10.5 to 11 if I stay at 62mph. If I bump to 65-70mph I drop to 9.5. Speed at those loads with the larger frontal area of our FWs makes a huge difference. And complete agree with the 13-14mpg towing 12k# being a pipe dream.
I tow about 11.5 with the Ram in my signature, in the NW not many flat tows I get between 10.5 and 12. I also don't take it easy in the hills, nothing worse than holding up and impatient driver climbing at 40 or 45, I can do 55 up all but the steepest grades, then it is 50 for a bit.
