My Sprinter camper and I parked next to this truck at Northwest MogFest in August and I got a good tour of the unit and spent some time with the pleasant and knowledgeable owners. Whether you like it our not will have a lot to do with your travel and camping strategy. As noted, the sturdy shipping-container-like cabin will lift right out of the back of the bed, leaving you with a fully-functional cargo Mog. But this means that there is no pass-through from the cab to the cabin, which would be a significant drawback to some.
It's also the case that, in true expedition fashion, storage has been maximized, with drawers, bins, etc. everywhere. Great if you're on a very long trip, but if the truck is mostly going to be used for shorter trips, you might prefer a different layout.
On other thing for US potential owners . . . because of the ease with which the cabin comes out of the bed, I believe US Customs would almost certainly subject it to the 25% cargo truck duty, rather than the 2% duty on vehicles that are indisputably RVs. But I don't know whether, due to NAFTA or some such, the situation is different when importing from Canada. Worth checking on, given it's about a $9200 difference.
