Background - 2011 Dodge 6.7 Cummins, 6 speed manual transmission, Crew Cab, Long Bed, Trailer is Wildwood 25BHLE (GVWR 7680, 26ft)
1. Yes I use my cruise control towing when conditions permit, which with my setup is most the time. Exceptions - winding roads, mountain highways, grades. I feel I have better control without it in those conditions, this includes being able to brake for critters who appear on the roadway,
2. I use the exhaust brake most the time, towing or not, with the manual transmission it is amazing how great it works, even with daily commutes. I don't think it has any factor on the gas mileage as it only engages when the your foot is off the accelerator. While towing, I can descend most grades without touching the brakes while even passenger cars and SUV's (not towing) are riding their brakes. I would never want to go without it again!
