Our BR A/C is not ducted. Meaning it only cools the BR unless you use a seperate fan.
During the hotter days (90+) down here I wait until the LR A/C (set at 73) starts loosing ground to the heat. When the inside thermometer gets up to 77/78 I kick on the BR A/C. I also use a fan in the BR blowing toward the livingroom. This system has worked at keeping the overall temp in the trailer in the mid to hi 70's when it's 90+ outside. Using the LR A/C alone the overall temp would get into the mid to hi 80s.

At night, I set the LR A/C at 77 and leave the BR A/C on. Yes the bedroom does get chilly but for sleeping that's the way I like it. With the LR A/C set at 77 it rarely runs at night giving it a much needed rest after running all day.
