Designer fantasizing IMO.
Pretty cool concept, but looks designed by people who've never camped.
Looks like they had the idea looking at some USB stick.
I had the same feeling when I first looked at Safari Condo's Alto trailer
. Although it is a actual trailer on the market, good looking, well made with high tech materials, super cute, etc, IMO it has a poor floor plan, very little storage, questionable durability, and is incredibly expensive. Seems designed by someone who've never camper before. Yet, many seem to like it enough to buy it (not me) so who knows...
2500-3500 kg is pretty heavy (in our FG world at least) and I suspect the final design will be somewhat different than this proposed one. There are things that I just don't see working right, or reliably.
