Just wondering if anyone is familiar with roads heading north from Greenville, SC to Johnson City, TN. Going to a small campground (Riverview) near Jonesborough, TN ( National Storytelling Festival 10/1-3/04) Only time I've been that way lately I wasn't concerned with pulling anything. Pulling a small 5th Wheel - with a 5. 9 gas/3. 55 rearend/auto. Ya, I do need a Cummins, but for now I can't get one. Anyway are there any long grades going that way? I'm leaving from Atlanta, GA by I85. (Atlanta looks flat till you start riding a bicycle around here)
