They are yet to present the prototype to the public, but it looks promising. Tufport makes some real good shells, but they haven't been any news for about a year now anyway ( compare https://expeditionportal.com/forum/threads/tufport-overlander.227945/ ).Any links?
Also, the Sherpa has a dry weight of 1600 lbs. Unlike many manufacturers, that's probably pretty accurate, but you are going to be way over 1/2 ton GVWR loaded up. Add people, dogs, water, food, stuff, toys, etc... 2500+ lbs is more like it.
I guess it's smarter to go with a converted united like the Sherpa.
