Carl, be very careful with the Climate Right. I bought one for our Little Guy teardrop, tested it at home (shore and generator
power), and drove to Alabama in the summer where it refused to cool (no refrigerant). Climate Right sent me a new one without even asking what went wrong. I must not have been the first with the problem. I still had to endure Alabama with a broken AC.
The new one I again tested, though for longer, then drove to Missouri in the summer. It was DOA, same problem. The fan would come on but the compressor would not engage. No refrigerant. We survived with a Lowes $110 window unit with ducts made from the box it came in and duct tape. Climate Right refused to replace it since it was more than a year after the original purchase of the first unit.
Taking it apart (since it was a $500 door stop at this point) you can see where they cut corners and don't put in vibration dampers on the copper refrigerant tubes and coils.
You can look at the glowing reviews on their website, but try to find a place there to submit a review. Tells you something.
I spent a lot of time installing the ducts and building a mounting platform for the Climate Right and never had it work except in testing at home. I will stick with the window unit that our Snoozy came with and replace it with a Lowes/Home Depot/WalMart unit if I ever have to.
