Hi All! Pretty serious about changing from Class C motorhome to Truck-trailer combo, due to overall costs associated with driving it. The biggest trailer we're looking at is about 8,000 dry & 10,400...
If the wet weight is over 8k then you will be better served by an HD. With a 7k dry 8k wet 33.5' ball to bumper aero nose box TT I average 14.0 on the hwy at 65. Thats with a tuned Ecodiesel. Any faster mileage drops off quickly.
