This is our second season with our 195RB Baja. We have the 8K BTU side-mount A/C and for the most part it does the job. I don't think it circulates the cool air quite as good as the roof-mount units, so we carry a 12V DC 3-speed Fantastic fan for the hotter days. The combination of the two works well. One thing that we noticed on our last trip to the south west in mid-April of this year - the stock window blinds are useless when it comes to reducing the heat coming in the side windows. That has been rectified now with some sun screen inserts for those windows.
As for the fridge performance - we installed a vent fan behind the top access panel on the outside above the condenser unit. It has a thermistor on it and will come on automatically when the temperature increases. Increasing the air flow over the condenser unit will improve the performance of the fridge. In general we have found the fridge works better running on propane but after adding the vent fan there was an improvement when running on A/C as well.
