POLL about your Air Conditioning

Just drove through the midwest and Deep South during two weeks of temps in the high 90's. My coach has two 15k roof AC units and has full ducting vs just dumping air out of the AC units.
We also put reflectix insulation between the shades and windows in the back bedroom and powder rooms which helps immensely. (We also put the reflectix in the windshield behind the drop down curtain when set up at RV parks and it makes a huge difference...like 10-15 degrees)

We found that running everything on Auto while driving kept the whole coach cool (low 70's) even with temps pushing 100. We did keep the genset and AC units running throughout the day during rest breaks, meals in restaurants and shopping stops. Felt it was easier to maintain temps than to try to cool down a hot coach.

My coach only had 18,000 miles on it but I decided to have my service guy check out the dash air. Found that I had a bad valve up front and a leak in the line that runs from the engine to the coach AC unit. What's interesting was that my good Sam warranty only covered the valve up front but not the line. After he was finished, we got a 26 degree temp variance....maintenance is critical!

We learned a valuable lesson when we were shopping for our coach. By chance We decided to shop on a really hot July weekend (90's) where there was an RV show on a mall parking lot and learned quickly the quality difference between the various makers (relative to cooling). Really opened our eyes and As a result, we bought an older model higher quality DP vs a brand new entry level DP. Glad we did!

BTW, we have a 2008 National RV Pacifica 40e
