Thanks to all for the helpful info. It was 102F on Friday, but only 90F today, so the AC was able to cope better. I do have a new 13k AC in the bedroom, but it will not turn on for some reason. Our trailer is a new 2012 Cameo, and the front AC worked at the PDI, but will not turn on now. Our dealer is a $200 drive away, so I'll visit a more local RV dealer to check the AC out. The reflectant cover for the windows in the direct sun make sense, we'll check this out too. Overall the Cameo has been great, super quality and nice to camp in. Thanks again.
