We have a Sunseeker 2300 Chevy. I think it is very similar to the 21QB. We have about 2000 miles on it, just got it. MPG has improved with each tank. The last one, we got 10.0 averaging 65 MPH on I-10 from Las Cruces to Tucson with light headwinds. I was running 70 for a good stretch, even. These are hand calculated, but the computer matches the calcs to within 0.1 MPG.
At 65 in 6th gear, it runs just over 2000 rpm. At 70 it runs about 2200. It doesn't have an instant MPG readout, just a resettable average. Instead of looking at an instant MPG reading, I find that watching the RPMs does the same. If I can keep it in 6th gear, I'm doing good. Having 6 speeds, it doesn't take much to make it downshift to 5th. In 5th, 65 MPH is about 2500-2600 RPM. It's smooth and has very good power. We are not towing, so I can't comment on that.
Our previous MH was a 23' B+ with the same motor and a 5 speed on a 3500 chassis. It was more aerodynamic, and we got 11.5-12.5 at 65 with it. The Chevys do real well for MPG. I do better without cruise control than with it. But I do use it when it's flat.
And they handle good too.
