2013 Keystone Cougar High Country 321res 3 slides

Thanks
My last trailer was ten feet shorter and no slides but cooled down with a 13500btu guess I was expecting close to the same. I noticed today that the exterior side walls on the slide outs are black and so hot in the sun I cant keep my hand on them. Thinking of painting them white or some sort of sun shade. Would not have thought of infrared camera. Now I have some options on things to do.
