It was just as loud in my '05 Designer, too. At some point I plan to look into getting it quiet.
BTW, I did manage to get my generator installed this weekend. It was surprisingly easy considered I had no help. I had it sitting on the back of a small trailer that I use to haul my 4 wheeler arond. I took the rear gate off and used the 4 wheeler to back it right under the pin and up to the front compartment. I then lowered the 5er down until they were level and then just slid the 300 plus pound sucker in the hole. A trip to Lowes for some 1 1/4" EMT conduit and fittings and the exhaust was all complete. Fired it up yesterday and it powers the entire 5er just fine. Looks like it came installed. One question I did have is why there is an extra fuel line coming off the fuel tank?
