V-10 noise.
I had a Tiffin on an F-53 chassis. The first time I pulled a small hill, I thought the engine was going to explode. It downshifts at the drop of a hat, and screams like crazy, but the 3 valve short-stroke engine does this, and does no harm to the engine. The engine makes its most power over 3000 RPM. It is a great engine, bulletproof as is the 5-speed tranny. It also makes the coach pretty responsive. I now have a Vegas with the 2 valve V-10, 56 less HP., but still pretty quick. It is noisy, as well, but the lighter Vegas doesn't need as much downshifting, thus doesn't scream at all. There are several programmers out there that can change shift patterns, which would make the coach much quieter, and sound deadening in the doghouse would help a lot. The V-10 is a very reliable, long-lived engine with very few issues. It is definitely not an economy engine, gas-wise, but it will always get you home.
