Yeah, but Roadtrek just spilled the beans on lithium ion. How is that going to go over? I think they have more up their sleeve on that Campskunk van. For one thing it appears they have installed way more solar than they need coupled with lithium ion batteries not to be doing something with air conditioning. Since there is none on the roof, I am guessing a 12V marine hull type installation inside. I'm aware of the avowed Campskunk claim of following seasons and climate to avoid air conditioning thus not needing it. I do much the same but then I am not full time and can plan a little bit more definitely. There are times you cannot avoid it like get invited to a B social in Kansas in July.
Also, I find it hard to believe Roadtrek would go to the trouble of sending out an experimental testing B as sophisticated as they are claiming for development purposes without it, needed or not. So, they will tease and slowly spill more beans. It is hard to suppress a secret you are excited about.
Advanced RV had been testing lithium ion batteries for more than a year that I know of, maybe longer. Some stuff I knew about but not all. Last month they finally made a formal announcement about it and it is their standard package offering. There are some other things I know about deliberately, accidentally and sleuthingly. I know of some things tested that didn't pan out and some things I have been asked not to say anything about yet until proven. You can't not know a lot once you commit and visit the factory. They are pretty much an open book dealing with a lot of customers on a custom development basis. I'm continually surprised by the things other customers have brought to the table such as Aeronie's composting toilet. It seems like a community development effort pooling ideas led by a company that stays open to most all ideas. It's been kind of exciting. Since they don't have dealers to keep happy they can concentrate on customers.
