I don't have anything to compare mine too. The genny is the standard 20 Kw Kohler. It is not very loud at all outside the coach, but the low frequency rumble inside the coach is very noticeable.

The previous owner had the exhaust system replaced. I am wondering if that could be the culprit? He had the shop move the piping pretty close to the bottom of coach to keep it from dragging. I am thinking either the replacement muffler is not up to the task, or the mounts are not doing a good job of isolating the exhaust pipe from the coach.....

Hmmmmmm, I should disconnect the mounts temporarily and see what happens. Gee don't you hate it when your brain kicks in.

Anyway, how loud is yours inside the coach?
