Hy,
i was also searching a lot in the spring 2012 for some SMART shipping compagnies who let you sail along with your camper from Canada to Europe and back.I've found NONE. i've called directly the shipping lines, was ok for the camper, around 65$ cubic meter for shipping the camper but won't take passengers. what a convenient way it would be to get off and having your camper ready to go. no planes, taxis , hotels and other fuss.
what i found there is 2 compagnies meretvoyages and voyageencargo for travelling by cargo but they won't arrange for the camper and i couldn,T contact those cargo who take passengers directly.
it seems to be a ferry to columbia but it's very not sure.

i thing the way to go is to find the cargos who take passengers and arrange with the owner of that cargo directly
FRom Europe to North America there is no ferry for passenger/camper. to Halifax would take 1o-14 days from Europe. there are around 2000 camper coming to North America each year!!!!!! do some math a lot of money guys
there is Grimaldi From Europe to South America, another ferry from Columbia to Panama, and there should be another one from North America to Europe to close the circle.
So i sold my Sprinter in Canada, i'll buy directly in Europe next year, untill having a ferry service from Canada to Europe
for theft issue i was thinking of a temporary shipping divider between cab and camper space like a wood plate or a flexible metal grill with some 8-10 attach points
also i've heard some shipping compagnies don't want anything inside for the shippment , others tolerate things inside
let us know if you find more
