Non-North America places that have RVers?
The only place that doesn't is Antartica, and maybe only a few in Greenland.
I have traveled a bit around this old world, and am pretty sure I have seen RV's on pretty well every continent.
Might be a bit scetchy in some of the poorer African countries, but people still camp out in overland style RV's there.
Motorhomes sales have exploded in the Scandinavian countries in the past 5-10 years. Also in many European areas as well.
If you plan to head for Europe, be sure you have a good sized bank account. Fuel prices will shock you!
Happy Glamping.Norman, 2008 Winnebago Adventurer 38J, W24, dozens of small thirsty ponies. Retired after 40 years wrenching on trucks! 2010 Ford Ranger toad with bicycles or KLR 650 in the back. Easy to spot an RVer, they always walk around with a screwdriver or wrench in one hand!
