RV travel to Canada

The other thing not mentioned here is: Go through the correct lane! It sometimes isn't easy, for example in Port Huron Michigan cars and RV's go through together, in Detroit (the Ambassador Bridge) there is one specific RV lane (entering the US), if you go through the wrong one it could mean a secondary inspection. 30 minutes is a short time, it used to take us 2 hrs to get the documents to enter Mexico, it didn't help that the folks at the kiosk didn't speak English and we didn't speak Spanish!
