I'd like to convince everyone with CA units in some other conversion the simple fix would be to jack up the CAs and slide a Liberty under them but there is more to the issue than that.

I don't think there is a single simple answer although Greg's addition of a second fan to supplement the squirrel cage fan sould like the simplest answer. I still suspect a great deal of the problem (apart from trying to cool a condenser with air heated to very high temperatures radiating from a highway) is the failure of the intake air and the exhaust air from the condensers to be separated. A baffle or some type of separator is required if there is any possibility of drawing hot exhausted air back into the condensing unit. I have a center baffle that absolutely stops that type of circular flow.

If that baffle was missing when I bought my bus I would have never known of it. How do you know it is missing if you have nothing to compare it to? It did not take long to recognize how critical that simple barrier is to successful CA operation. I don't think the designers of the CA or our converters are stupid. I do think the locations are a compromise, but when properly charged, and all baffles are in place the CAs work quite well under all but extreme circumstances such as when driving down the highway in the desert Southwest at 3:00 PM when the ambient temps are in excess of 105, and the blacktop has reached temperatures high enough to frie eggs.
