I ran into the heat problem----------
I ran into the heat problem here in Florida with a 15 K A/C would not cool down my 8285WS. I found the factory dark windows that were installed transmitted so much heat into the interior of the RV, the A/C could not keep up.
I applied a window film from Lowe's called "GILA Platinum" to the interior of the windows. WHAT A DIFFERENCE in cooling. My A/C now cycles off and on after the RV has cooled down from a "SET UP" in a RV park. I am no professional at applying the film. If you are not good at it, you should have a "TINT" shop apply the film for I wasted a lot of film trying to get the wrinkles out! I also used a "TITANIUM" film also on some of the windows. I remove the plastic skylight in the bath room (the one attached to the white plastic trim) , had a tempered "GREY" tint glass silicone back in the place of the clear plastic on the skylight. STOPPED 90% of the heat in the bath. Just these little changes has made a great difference on how the A/C works in cooling the RV down.
