was curious to find out if any one else has had this problem:
We have a 2018 RPOD 179 with a DOMETIC 13,500 BTU AC, purchased “New” January 2019. Our first trip was to Newfoundland, summer of 2019, did not use the AC much. Upon returning to the US, we began to notice a rattle noise in the AC when used. When we returned to Florida, took it to the dealer as it was covered under warranty. Allegedly repaired it.
We had planned to return to Newfoundland this year but due COVID 19 it was impossible, so we are cruising thru the south. After a few state park the AC began to rattle again, I could reach up thru the duct and actually move the fan motor and it would stop. Only to start rattling again when we reached our new camp site. We finally able to get on the roof and remove the AC cowling, and discovered that both bolts that held the fan motor in place had vibrated out.
Our fix was to reinsert bolts with lock tight on the threads, hopefully this will do the trick. Fan motor is not rattling at this time.
Hope this helps.

It finally got hot enough to test the noisy ac repair job. Hooked her up...put it on 55...and waited...my abused ears with hearing aids heard the sound of wind rushing through the unit.

A new 12000 btu minisplit is whisper quiet and much more efficient. So it can be done. The problem I think with the roof a/cs is that you have to have two itty bitty holes in the 14 inch square opening to take air in and out of the evaporator. So high air velocities = high noise levels. The minisplits have the evaporators inside so can have a larger cross section and reduced air velocities.

offgrid, have you installed one in your Pod?

No, I was planning to give it a try when we lived down in the flatlands but am holding off for now. It triggers off a major set of mods including a new ceiling vent, inverter, Li batteries, dc dc converters, roofmount solar, MPPT controller etc. Total cost would be about 4-5K but that would give me off grid a/c for about 8 hours a day from solar, longer with generator operation in daytime. Not sure we would get the use out of it now that we've moved to the mountains and don't need the a/c as much.
I do know that the 9000 btu Pioneer Hi SEER evaporator will fit over the bed on the drivers side in my 179 and the condensing unit can go on the tongue but the batteries would have to go to make room, and the propane cylinder would need to be moved forward about an inch.
I have installed several mini splits in houses I've owned and loved them. They have variable speed motor drives so they slow down and speed up rather than blasting cold air and then cycling off. I do get an a/c tech to do the final pull down and hookup but you're not supposed to need to. My biggest worry is that vibration from travel in the connections at the condenser will cause a refrigerant leak. There are flex lines available but they have a spotty record.
