Pardon my greenness. I am 100% a newbie when it comes to RV’ing. I have a 33 ft class C, 30 amp, that has a single AC unit. The fan in the bedroom is pre-wired for a second unit, so it should be easy to install, I live in Arizona so the second unit would be nice to have.
Obviously, the issue is power, or more specifically startup power. I have been working with the math and 30amps is enough to run 2 AC units once you get past that huge initial startup draw. In doing some reading it would appear it should work just fine using products like easystart or softstart.
I guess my question is, why are RV AC manufactures not including easystart/software capabilities directly into the unit? Or, are there actually units out there that does this and I can’t find them? It would seem like this would be a no brainier especially with the RV power limitation?
To answer your last question. Some RV OEM's do install a Pulse type system for running 2 AC's on 30 amp. But it is RARE for BOTH to run at the same time. It gives you the option to run the Front AC during the day and then running the bedroom at night where you want to stay cool. Doug
This is a system Jayco installs. Other OEM's also use it
