I couldn't be happier with my 8.1. And I'm super glad I didn't go with a diesel. I can get a new drop in block for the same price as a turbo on a diesel, so when it comes to repairs, I'll be cheaper in the end. Besides, the 8.1 was a marine motor. If boat owners can depend on it to not break down in the water, then I can depend on it to not break down in a 12 inch snow storm. Just want to add also, if I was running my dump everyday for everything I do, then it wouldn't be economical and a diesel might have been better. But, to have a dump with plenty of power and dependability to get used whenever I really need it, then I feel I made a great decision.
