[2004 Itasca Horizon]

Yes, the duct work could have come loose and sucking warm air.

I have found with our basement air that approximately 15˚ below outside ambient temperature is what to expect inside, so 90˚ outside should be around 75˚ inside. The AC will most likely not cut off.

Once when we were in temperatures above 90˚ we went to Lowes and purchased some "space bubble."  It comes in rolls and I cut it to fit each half of the big window. Half a window at a time because it was easier to manage storage.  When I put it in the window the temperature dropped inside to a comfortable level.  Even though the windows are double pane the heat emanating through them is very high when the sun is shining in.

We have stayed at Railside RV park and enjoyed it.  Nice doggy sitting service - the (at the time) would come and let the dog out and the fee was extremely reasonable for doggy service.

We used one in San Antonio recommend by the CG and they did a fine job for $80. Forgot the name but i can find it with a phone call.
