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...
A 10K GVWR trailer would be at the limit of most 1/2 ton trucks payload and handling limits. That size trailer would put many gas engine trucks in the 8-10 mpg range, depending on what speed you tow.
