Fully Electric RVs are comingWhile it will be a couple of years before mass availability/adobption of eRVs, the trend is there and manufacturers aren't sitting on the sidelines - as some did for the car industry...
Interesting article below, concluding with:
"Both of those solutions (hydrogen and solar complementing electric) help solve the issue of driving range but underscore the need for serious, high-power charging infrastructure at campgrounds—and elsewhere, with physical layouts that work for RVs and trailers. Who will step up to deliver this? It’s another chicken-or-the-egg, all over again."
To the question above, I think that, with today's announcement, we can legitimately say that DM EVS is stepping up to deliver part of the need - hence helping address the chick-or-egg dilema.
