2019 351M loaded. Has 3 AC units, two work great. Rhe one in the bedroom blows tepid i guess you could say, not cold but not hot. Filters are clean...on an 82 deg day it will barely get the temp down to 74. All the windows are tinted and i have additional blankets on them on the "sunny side" to help keep heat out, and trailer has the extra climate insulation package. Coleman Mach. Can you recharge these things or a temp sensor maybe
