I was all sweaty and dirty and wondering if it was all worth it.

It was. Like was said earlier, we can’t really hear the engine running unless we stand on the gas pedal and have it drop down to the lower gears due to a big hill or in passing. Cab is also cool as a cucumber. It’s quieter than one of the cars that we have and should have been shipped this way.

Btw, took extra Dynamat (both kinds) and wrapped up my A/C covers & also did the same around my generator.

My genny’s much quieter now and my A/C maintains a noticeably cooler temp as well.

Yeah, What Cwray said..... us the thiner asphalt first then follow with the thicker suff. I used some of the Noico brand but its not as sticky as the Dynomat and Fat Mat brand IMO.

I also used some Fatmat around the generator area (On the access door + floor of the RV ) but it really didnt much much difference since all of the sound come from underneath my RV (not from the side and not from the exhaust). And I have to leave the bottom open so it dont over heat the genes. I have some cardboard I can lay one side of the RV to redirect the sound if needed. You can also put down some cheap carpet pieces down to help absorb sound (not reflect) the sound with causing an overheating problem.

Yeah my RV cab area is very quiet (and cool) now unless your accelerating. Im very happy with the results as well.
