I am also considering an A/C install on our 1300 but am not a big fan of the window location.
We had previously removed the propane furnace
from our trailer and I am looking at installing a portable A/C unit in the space previously occupied by the furnace
. The duct work from the furnace
has been retained and I am sure can be modified to retrofit the exhaust hose of an A/C unit.
Researching the dimensions and configuration of various models of portable A/C units is currently underway and any suggestions or tips would be welcome.
