I have to agree with Steve. It makes a huge difference when I mount the Shade Master front window covers on our coach that’s similar to yours. Keep in mind that even home AC units commonly only go 20 degrees below ambient temperature, and the nation, especially the south, are maxing out right now. You do have to accept that in summer in certain areas, there are just plain limits to what can be done.
When we spent weeks in Tekamah, NE, in 2012, humidity was worse than anything we were used to in NW Oregon and daily temps pushed 110 or more, and up to 90F inside. No wonder most of the Ashley’s moved from there to the Northwest in the 1920’s. In the city park, RV spots faced east. Thank goodness there were tall hardwoods in the grassy park behind us so afternoons brought shade. But we couldn’t have handled it if the Shade Masters weren’t shielding the interior, plus we could see out during the day while no one outside could see in.
Our covers were custom made on-site at our first FMCA rally for a good price, and match one of the coach colors.
