I own a 13 Washington and the livingroom a/c appears to be inadequate in cooling the temp below 85 even in the shade. Outside temp 89. I was advised to tint the windows but I don't think that will help a lot because it still had difficulty cooling in the shade. Has anyone else had this problem?
Donald, your windows are already factory tinted dark so I can't see that adding more tinting is going to do you much good. Here is a post below with others having issues with the cooling system on the Rushmore. This may be something Crossroads need to address.
