13.5k vs 15k AC

[LGC]

My 31' 5er struggles to stay cool with the 13.5k. Would I realize much difference by going to a 15k? I have a single ducted unit and 30 amp service. I get about a 15 degree drop in temp at the discharge (65 degrees at 90 degrees ambient). Looking for recommendations if I should change to 15k, best A?C units or other considerations.

Last year I replaced my Coleman 13,500btu with a Furrion 15k HE unit. I too only have 30 amp shore power but installed a Microair easy start on the furrion unit which now runs great on my 30 amp.

To change I purchasedbthe coleman Mach to furrion conversion kit which allows use of Coleman control box, thermostat, and wiring. Did lose the low speed but really no loss as I never use the low speed which often just leads to icing of the unit. Leave on Auto and life is comfy.

My trailer cools rapidly and is a lot quieter, especially when I also upgraded the air distribution box to Furrion.

My biggest problem seems to be a lack of insulation. I just took some temp readings and was taken back by how hot the rv gets. On a 90 degree afternoon this is what I found:
Inside wall shaded is 82*. Direct sun side is 89*.
Outside wall shaded is 89*. Direct sun side is 115* on white paint and 123* on tan paint. RV is mostly tan.
Inside air is 85* even though the AC is blowing 65* air.


It appears that I need better air flow to effectively cool it down.
