I bought some used parts from a 2007 Montana camper last weekend. He also had a power distribution center he called it. It is an Iota power distribution panel with fuses and breakers. It had a DLS-55 DC power convertor. He was wanting $150 for that whole setup. I didn't buy it because I wasn't sure if it was a good deal. If I bought it, would it work for a basis for my electrical in the bus? I assume with a system like this, I can hook up to a battery and it converts it to 110v ac? I notice it plugs in. Does that charge the battery up when you are hooked to shore power? What else would I need? I would plan to get some wiring with this as well including the battery cables. I'm wondering if I should go back for this system. It's about 1.5 he drive away...
