A/C Condenser Evaporative Cooling Assist
I am wondering if any company offers an evaporative cooler designed to reduce RV A/C condenser inlet air temp to assist in 95+ deg temps? I designed such a system (inspired by some mechanical engineer...

I like the idea and would love anything that would make RV AC more effective or efficient, and wish you the best of luck overcoming the issues with using water to assist the condenser in an RV.
In the meantime, it seems to me the effort is best spent just using a much larger condenser and much larger condenser fan for increased efficiency. Of course then we would need a variable speed condenser fan and compressor to keep the pressures in check, maybe an electronic TXV, and a computer to run the whole thing. This is starting to sound like a modern mini-split!.
Most current RV roof air conditioners use 1960s/1970s window banger technology. They could make a rooftop RV air conditioner with a very superior performance and efficiency to what's available now, but it would be $4500 instead of $800. You and I may buy one for that, but unfortunately we are the minority RV buyer at the moment.
We do have the Coleman Mach 3 PS 13.5 which has a higher efficiency compressor (scroll I think) and larger condenser compared to their standard 13.5 Mach 3. Currently only have 15A service in our back yard where our trailer is parked and that works well except in the middle 9f Aug. in full sunlight.
