I just purchased a 2021 Roadtrek Zion SRT and I’m finding it hard to get answers to some questions. They don’t have a very helpful website. My first two questions are how do I monitor the two lithium battery levels and the air conditioning does not seem to work. The air/con blows but does not drop the interior temperature. One of the reasons I got the Zion is because of the electrical setup and the 11000 btu air/con which should be plenty. Any help?
