I have a 35' Montana with a 15k a/c about center of trailer. I want to install a a/c in front bedroom, which is factory prepped for it. Just a non ducted unit. What size btu should I be looking at?...
Most go with a 13.5K low profile for the bedroom (which is what ours has). We spend time in Georgia, South Carolina, south and central Texas and the southwest. The 15K/13.5K combo does fine.
