We haven't had time to do much about our cooling issue as our RV has been with the dealer. However, we got it back a few days ago and immediately got some Reflectix from Lowes and covered the windshield inside. Under the exact same outside temps and location as before, we are 4 degrees cooler inside with just that one change. Big enough difference to go from unbearable to tolerable. If you're having trouble keeping your RV cool I highly recommend you try Reflectix on the windshield for a quick, easy, and cheap initial fix.
