I'll freeze you out of our 40' fiver when running both our 15000 and 13500 BTU 
A/C's, and yes this is in 94° heat with zero shade.  Set up fiver in driveway over the weekend prepping unit for trip and had to turn bedroom unit off when it was down to 74°.  Main A/C is ducted but I had the dealer block off vents to the bedroom so it now only cools the front living room, kitchen and bathroom.  Keep bedroom closed when not running bedroom A/C.
