Purchased the iGen2500 a while back in hopes that it would run the Cool Cat AC on our 2021 400 BD. I know some people browse the forums to see which generators will work with T@Bs so hopefully this info is helpful.
I just did a couple of test runs in 100 degree weather here and it appears to run it just fine. I’ve yet to try it for long periods of time though. I haven’t tried econo mode yet either. Just glad it runs it.
