Portable Air Conditioner?
As we spend most of the time in the desert with temps well north of 100F, good a/c is something that we really need. I have 13.5k units (ducted) and could upgrade them to 15k units but I am conside...

Tyrone and Bone - you are kinda missing the point. Single hose units suck air from inside the RV, blow it over the condenser and exhaust it out of the back. So they are taking air from the inside and blowing it outside.
The air that they take from the inside has to be replaced - it creates a negative pressure inside the RV so air enters the RV through vents, doors, leaks etc from outside.
At the same time, it also sucks in air that it passes over the evaporator which cools it and it blows this back into the RV
So the cooling has to not only cool the air in the RV 'box' but also has to cool the hot air that has been sucked into the RV.
A dual hose unit sucks outside air in and blows it over the condenser and then blows it back out of the RV - the only air being sucked in from the RV is blown over the evaporator and back into the RV.
On one of the web sites, they ran a comparison of how long it took to cool down an RV from 88 to 73 - the dual hose unit took 22 minutes, the single hose unit took 89 minutes.
Mine should be here tonight so I'll post some photos as I install it and report back on efficiency and noise levels.
