gp/Gail,
The AC was installed by the manufacturer of my TT. When I first move into it, I noticed it wasn't draining anywhere! The handbook didn't address that issue, so I had an RV tech come out and he took one look at it and said that unit recycles the condensate. I was skeptical so I called Frigidaire and they confirmed it. The unit is designed that way. It does have an overflow tube for humid conditions when there is more condensate than can be recycled.
So, the TT manufacturer cut a hole in the side of the TT, built a cabinet on the inside that looks like any kitchen cabinet, but without the door, placed a drip pan on the floor of the cabinet and installed the AC sitting in the 1/2 to 1" deep, three sided drip pan, with about a 15 degree slant towards the outside. The drip pan open edge is right at the outside wall edge, and there is a screened cover over the back of the AC. The cabinet was built so that the unit is fitted in it quite tightly, it isn't bolted down or anything.
Now, the TT dealer told me that in very humid conditions, they have had people complain of water overflowing into the inside. I am in central Texas, over 100 degrees and over 50-60% humidity. No problems and have been using it for a month, running 24/7.
The park I am in doesn't allow window units that hang out! This looks fine inside and outside. It's plugged into a regular A/C outlet (I am in a full hookup site for now) inside the kitchen cabinet (like a built in microwave) and my bill this last hot hot hot month was $46 (we pay our own electric). My TT is a 15 footer.
It's a pretty cool air conditioner (sorry). Oh! The fan runs continuously, unlike other units that shut off when the cooling part shuts off. If you are noise sensitive, I wouldn't recommend it. It isn't especially loud, just know that you will have that continuous white noise.
