Trailers have two major problems. Large surface to volume ratio, and lots of windows. Windows, no matter what you do have a low R factor. Then the fact that for the trailer volume you have lots of exterior surface area heating up, no matter what the insulation is.
I'll contribute a 3rd.
Ducted A/C units run their ducts through the very thinly protected (often no insulation from the roof surface) ceiling, which heats the air before it ever gets out the vent.
I've read about some folks adding reflective insulation to the inside of their A/C shroud on the roof. Not sure if it really helps or not?
Our inside shades have day and night shades, which help keep the sun out, but likely no other "R value" ;)
