AC Quiet
The noise from my Dometic AC in my travel trailer has been deafening--far louder than the motorhome we owned previously. The noise wasn't coming from the compressor, you could hardly hear it cycle off/on over the roar of the blower.
I read a lot of posts from others here and on other RV sites and most said, that's just how it is with a non-ducted system. I decided to see if I couldn't improve upon that so today I went to my home away from home, AKA, Home Depot and picked up two rolls of closed foam tape. I took the air distribution box down from the ceiling. There are 8 screws that hold it in plus the knobs that just pull off. Four are a little hard to find, you have to remove the louvers on each end to get to them (carefully pry them out). Leave the knobs for last.
When I got it down I saw that the bottom of the air distribution box is pretty well covered with a very thin sheet of closed foam, maybe 1/16 of an inch thick. This is most likely to prevent condensation from collecting on the box. I took my sclosed foam tape which is 3/8 thick, cut it into strips and covered that thin sheet. It took most of the two rolls. I'm sure you can get that product in a sheet which would work better, but I wasn't sure what I was getting into till I took down the box.
I reinstalled the air distribution box, connected the trailer to AC power and fired up the AC. It really made quite a difference in the noise. I am very pleased with the result. That was about $12 well spent.
Can't wait to get on the road again and test it in the "real world".
