I like the concept.
But is it realistic ? not really!
With a GVWR of 6,200 lbs there are no small vehicles that can tow it, and even fewer EVs, not even a Tesla X, not even a Tesla X Plaid!
And for EVs that could tow it, at that weight it’s pretty much mandatory for it to have propulsion assist.
Even many F-150 models cannot tow it, and a F-150 Lighting only with the add-on “Max Tow Package”!
