Has anyone travelled Newfoundland in a 38 ft. 5th wheel and if so did you have a problem finding campgrounds for that size RV or maneuvering on the roads?
Tripalot is right about taking the shorter ferry trip.
Newfoundland and Labrador, a province abbreviated officially as NL, is sparsely populated and there are lots of places to tour and cgs or gravel pits to use on your return journey.
