Mach 15 a/c not cooling well
I have a 2020 travel trailer with a coleman mach 15 in a 33ft travel trailer, with 2 bedrooms. In the back bedroom I have a portable a/c with the door shut, that room is no concern to me other than it...

My trailer is 37' overall, and cools suitably well with a single Coleman 15k. One big upgrade I did however was slide toppers. Without these, I could feel heat radiating through the slide ceiling in hot weather.
If your A/C unit is not cycling, it's probably working as intended, and your trailer simply has a higher heat-load than mine. If it is cycling the compressor, you might have an issue.
Also, don't forget to check voltage in the trailer during peak A/C use. If voltage is low, your compressor will be pulling excess amps.
X2 to slide toppers! Makes a Big difference in heat transfer through the slide roof.
