Need to replace my front AC and am looking for recommendations replacing a Coleman 13.5.

........When you remove your A\C unit , take some of that foil backed tape and completely seal the 14"x14" hole in the roof ! Upon inspection you will notice many , many small small cracks that allow a significant % 0f your cold air to escape into the ceiling of your trailer . If your system has ducts in the ceiling tape them as well .
........The other potential problem occurs when the partition meant to separate cold air from return air doesn't exert itself against the bottom metal surface of the A\C unit ! IF , it isn't sealing as it should be , cold air will be sucked back into the return air flow . , jf

If you can- go to a 15,000 BTU unit. I was surprised at how much better it works in 80 degree plus temperatures than our old 13,500 unit.
