When camping in Bristol finding propane for our motorcoach used to be a problem. The pump trucks that serve the campgrounds gave us sticker shock, and we never knew when or if they would come. Last year we found propane at reasonable prices at Lakeview RV Park
www.lakeviewrvpark.com. It has easy access to the propane pumping station for big coaches. The campground is three miles from BMS on Highway 11 E toward Johnson City. They fill small tanks too cheaper than the exchanges at gas stations.
