My first experience with the Ford V-10 was about 5 yrs ago when I bought a used 2000 Rexhall Aerbus. I used this RV for 3 yrs and put about 30,000 miles on it driving from Atlanta to Montana, Atlanta to Arizona and Atlanta to Mexico.
I consider the V-10 the best gas engine I've ever had. Lots of power, smooth running and never had any issues. On the Montana trip we were towing a 4wd Chevy Suburban. The engine had 40,000 miles on it when I bought it, a bit over 70,000 when I sold it. Changed oil every 5000 miles and never had to add between changes.
The Aerbus had a 4 speed transmission, and would shift down to 3rd on most climbs, and 2nd on a few, but really didn't do that much worse then the diesels I've had. Expecting a motorhome, diesel or gas, to climb every mountain pass at speed limits speeds, is not going to happen.
