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?
I have a 50 amp fifth wheel so I think it is different, but my understanding in the 30 amp motorhomes is they run on one thermostat (mine has two separate thermostats). When one thermostat controls both, then I think it ensures that they do not try to start at the same time, which is how you can get away with 30 amps for two units. As stated, keep an eye on the voltage and make sure you do not run too much. Tripping the breaker is not a big deal, you can just reset it, but if the voltage drops too low bad things happen to the AC units.
