Heard ya'll sat a record temp out that way somewhere today Tex. :bleh: Had a shower here today and cooled everything down. I know Pat, we haven't helped you with your to cold and loud AC but waiting for the info Len asked.
The room space/area in a truck camper is small, therefore when you have a AC that is about the same size as the ones used in a large RV, you will be cold and it will sound loud because you are close to the output vent.. The a/c on my 30 foot 5th wheel is barely adequate because it has so much space cool. This sounds like a good theory.
