I just purchased 1995 Luxor and did our walk through on an extremely hot day. The dealer thought they had the coach cooled down but when we went it it was discovered that we had blown the breaker(on the outlet at the dealer, not on the coach). This happened a couple of more times before they realized we had the coach set on 50A and we were plugged into a 30A shore power outlet using pigtail. Now keep in mind we were only running the AC and a couple of lights. I was/am concerned that the coach was not cooling properly. I could certainly feel cold air coming out of the vents, but it was 95 degrees inside the coach, so anything would have felt cool. After an about two hours inside the temp dropped 2 degrees. The tech told me the air would cool better if we could run on 50 amps. My question is, is this true? Does the basement air run in economy mode at 30 amps, but has more power at 50 amps? Overall, what kind of cooling can I expect on a hot day? Am I going to keep the coach cool enough? Of course they told me it takes alot longer to cool the coach down when starting at 95 degrees inside on a 98 degree outside air day than if it was held at a constant temperature for a longer period? This is my first RV and I am just concerned that the unit is not cooling properly or is just not going to be able to keep things as cool as I want. Any words of advice would be greatly appreciated.
