I just purchased a 68 Globe Trotter and need AC as I live in Dallas. I do not know why but I just do not want to put the AC on the roof and have looked at portable AC's as an option. I have seen 12,000-13,000 BTU models with heat for under $600.00.
I would think a vent out to one of the outside access doors running the heat exchage under the front pull out would be perfect. Anyone have thoughts on this option? There are only two of us and I do not see space too much of an issue.
Another plus is that I could roll it out when not using the Airstream and cool off the garage when fixing it!!!
I would love to hear anyones thoughts about this. I assume 12,000 BTU's is enough for a Globe Trotter, at night the bathroom pocket door would be closed.
My only concern about floor-mounting an air unit would be that it won't cool very efficiently. The ceiling is where the heat is. A roof mount unit intakes that hot air, and blows cold to the interior allowing for the cool air to mix with the hot and cause convection throughout the system. I'm not sure that, at least in concept, a floor mount unit would work nearly as well.

I have used a portable for the past couple of years.
I made a cardboard template that replaces the screen in my back window. (Window cranked out) and the hot air is vented through there.
It has oscillating louvers that move the air left to right and fixed louvers that can shoot the air up or down. I supplement that with a clip on fan mounted toward the ceiling ... blowing downward. Condesate is drained through the shower drain.
This combination does a good job of reducing heat stratification
at the ceiling level ... but then again I dont sit at or near the ceiling ... I sit on the goucho's.
Granted I only have a 17 footer. The unit is a 9,000 BTU.
Total cost for a non profile ruining, not hauled around for 10 un-needed months of the year for not, solution ... $250.00
I am attracted to the fact that I can take this thing from the Airstream, use it in my garage, or in my home office where in the summer, my home AC never gets it as cools as I would like.
I bet 12,000 BTU's would do a good job cooling a 20 foot trailer-
Sorry, I fail to see the comparison of a motel room, that is part of a building, that is usually shaded on three sides, to an Airstream trailer, that bounces down the road, punishing equipment that was designed to sit still, and at the same time being exposed to the mercy of the sun.
Additionally, the motel AC units have a considerablty larger cooling coil than any RV airconditioner, let alone that of a household window unit.
Warm air rises, cool air falls. If the cool air is exhausted at the floor line, your feet will be comfy, and that's about all.
Mounting a window type AC, in place of an Airstream window, is not recommended because of the weight distribution, and, the shell not being designed to take added weight, especially when hitting bumps. If the trailer stays stationary, then that's a different matter.
All too many times, make shift installations result in costly repairs at a later date.
