Only 1 AC, but since it is only a 27 footer, hopefully that will work.
The previous owner added two 100 watt solar panels on the roof and installed four 6 volt AGM batteries, so I am covered there. That was quite an investment as those batteries are pricey. In addition to the batteries in the step, he added a battery box in the storage compartment next to the step for the additional 2 batteries.
I have a 2019 Sunstar 27PE 29'. Have had a few issues with it and did quite a few mods but pretty well got it dialed in now. Feel free to ask any questions.
