Typically Diesel engines have more torque and a much lower redline than gas engines. Consequently the shift points for transmissions connected to Diesels are much lower than gas engines.
Conversely gas engines will typically have more horsepower and rev higher.
The net affect of these differences is that in truck instances (motorhomes, pickup trucks towing trailers/5th wheels, etc.) Diesels will get you going a little quicker from a stop due to all the low end torque available but when at speed a gas engine will ultimately go a little faster on the top end (for engines with comparable specs).
I remember reading a Road n Track comparison of Diesel and gas pickups once where one of the tests was a 10,000 lb tow up a hill. The Diesel engines made it up the hill at a relatively constant speed and engine RPM. The gas engines started out slower but ended up passing the Diesel's up the hill as they picked up speed and engine RPM.
Basically when you're driving your Class C around don't be afraid to let the V-10 rev a bit higher than you're used to. It does get noisy--although I'd bet the Ford cab on the Class C provides better noise insulation than Thor does with the Class A cabs where the driver is sitting right on top of the V-10.
In addition: Expect the V-10 to be a lot more thirsty: 8-10 mpg.
