Window unit...

[OleManOleCan]

Gonna have to replace the Window air conditioning unit in my
Vintage 75 Fleetwood Prowler. Very Old unit is a goner...

I bought the 75 in February. The old window unit is cut into and framed in the
rear of my camper. PROBLEM...
None of the small units I have looked at are quite as small as the one that died.
I'm gonna wait for some dry weather, pull my old unit.
Buy a small unit, enlarge the opening to fit, and reinforce the opening,
then mount a new unit, and seal around it.

It's always something...

I bought a small Frigidaire for my shed it's only 12"x16". What size do you need?

The new ones are considerably more efficient. I'd love to have a mini split unit on my ride.

Have you searched Amazon, Ebay or other shopping sites to locate a size that will fit your opening.
