Driving a across Canada last fall was interesting. Very few campgrounds open so mostly Walmart and Husky overnighters. We found that small towns are better for finding dump facilities than larger towns. There is usually a small sign posted indicating if the town had dump facilities. Can't remember if any of them cost money but I don't think so. On the way back through the US we dumped at Flying J's Seems to me they were fairly cheap. We rarely stay in Campgrounds when dead heading. We don't need to dump that often. Seems to me we dumped probably 8 or 9 times in 7 or 8 weeks.
