We tow a 29ft travel trailer that comes in loaded about 6700, plus our stuff in the truck [with topper] so besides our 7540lb 2014 ram 2500...6.4 gas [full] ,camper, and stuff, about 15,000 total?..In regular mode, I seem to get about 8.5...now thats NOT in mountains and not alot of headwind and at 62-65 mph...in tow haul mode it seems to take me down to 7 to 7.5...but I sure feel better about that trans! Never see the trans run too hot though. As you know, it's cool that sometimes if nice and flat and no wind it might go into 4cyl mode once in awhile in reg mode! thanks for the Video!
