I've said to Mrs ShuttlePilot before that if my current van is a total loss for some reason that this is the route I would build as a replacement.
I'm surprised that today, in 2020, that no builder has offered a 2021 E350 cutaway, 4x4 conversion, a modest sized box like rear, aircraft quality interior, couple of kilowatts of lithium powered amenities and charge 200-225k$ for it. Bridging the gap between the now crowded Revel class and the Earthroamer class. Allan Feld are you listening?
I love this set up Abitibi
