UJoint Vans…ridiculously affordable and capable…and you could even do the swap in your driveway with basic hand tools if needed.
You would have to buy their kit and do the conversion up here.
It would be very difficult (maybe impossible?) to import a 4x4 van into Canada unless it was done by Quigley or other government approved secondary vehicle manufacturer.
Legally you can't even import a Sportsmobile as they aren't on the approved RV manufacturers list for Canada.
