When I was deciding what van to buy BSMB (BSMB=before SMB ), a Safari Condo camped next to me. I could stand up in it with out popping the top. It is made in Canada but I would have to buy a van in the USA and take it there, if I ever wanted to get it licensed in the US. Sounds like the same problem in reverse. Anyway, check them out www.safaricondo.com

There are a few of us Canadians on the forum with different experiences. Cranny got his in Portland. I was able to find a Canadian delivered van in Calgary as a platform for my build. You can go to a Ford dealer and start fresh or search used vans in Canada but you'll have to keep your fingers crossed. After I lucked out and got my E350 diesel 12 passenger I chose to have Clydesdale out of Kamloops do my 4x4 conversion and GTRV out of Richmond do my van conversion (went with a Transformer type conversion as opposed to full). I got Clydesdale to add the Espar heaters and GTRV did the Transformer with a T-top penthouse. GTRV will work with you based on your wishes. Check them out at http://www.gtrv.ca. If I were to do it all over again I would still choose GTRV (first class all the way).
If you buy your own vehicle in Canada and it is already registered, you can take it down to Sportsmoblie to have it converted. The Huntington IN Sportsmobile say they do quite a few.
Then at the border present receipts and pay GST and PST according to one local border crossing.
Have not found much in the way of Sportsmobile equivalent in Canada, the closest being gtrv in BC (604 304-3243). (Great West in Manitoba might do it if things are slow, and Sidewinder (BC) will do some work but they have to contract out any propane systems...)
