I agree 100%. The color will have a great deal to do with the heat absorbed. The rubber roof being tan does not help either. 125 sqft of mine is now bright white.
RV's are built to the minimum standards. There is a major difference in putting an RV in a closed building and turning on the heater to 100 deg and see how the RV does in keeping cool. Then take that same RV and put it out in the sun on a 100 deg day. The numbers will not even be close.
The outside skin will not get over 100 deg when inside the oven. I have recorded over 130 deg skin temp at 5 pm on mine. That is a 30 deg extra heat load the A/C's have to contend with.
I had several people walking by ask me if I was having cooling issues, having seen the sun screens I have up. My answer was not now, I am cool. By dropping the inside wall temps almost 40 deg in the heat of the day. I have taken a great load off the A/C's.
Last week with rear thermostat set at 78, I would get constant run and 83-85 inside temp. Now, I get 78 and the unit will cycle as it should. The front is not a problem. Much smaller room and I do have a little shade for it.
