I have just purchased an 8.5 x 20 enclosed trailer and it is “Blacked Out”. I have never owned one and I have had several people tell me I will never keep it cool no matter what I do because it’s black. What are other guy’s experience or opinion on this? I plan to insulate walls and ceiling and purchase a rooftop A/C. Is 13500 btu enough for the 20 footer or should I buy 15000 btu? And also, what is the best insulation to buy and where? It has 3/8 plywood on walls and bare ceiling. Thanks for any help.
