Works great, I was lucky and got it from the Revain warehouse. I can't imagine spending more than $900 on it. But for the price I got it's amazing. The internal fans are louder than expected, but not bad. I will say one thing when you connect to shore power with ATS. Make sure that the energy saving mode is deactivated. The energy-saving mode assumes no load and does not operate the switch. I learned this the hard way π€¦π». This will power everything in my Toy Hauler. I haven't tried it with AC devices yet. But if I need to run AC, I just use the onboard generator. Although I think it will power one of the blocks with no problem. Well done, come in force!
