Perhaps. A sprinter van will take a ton of weight too and be better to drive.
A Sprinter will take less than a tonne and be better to drive on a sealed road. A cab over truck like this one will take well over a tonne but do much better in driving crapper roads.
Here in Oz, I would take a cab over truck over a Sprinter as an expedition vehicle every day of the week and twice on Sundays. No question. And if I wasn't going remote then I would get a much smaller van than a Sprinter.
