I've had both the 8.1 Chevy and three of the Ford V-10 power trains. One of them in a 31 foot class c. They are all noisy, especially on a long climb. We Traded the Class C for our first A, but had to go with the Chevy. Loved the coach, but hated the Chevy/Allison combo, so traded again to get back into a Ford. For me, the trade off has been the better climbing torque and better fuel economy of the Ford. And now on the new unit, Ford has made a dramatic change on the A suspension. The only way I'd change from the Ford is to go with a DP.
