I just drove across US84 from I-65 to the MS border and what a roller coaster of a ride
!!!
My truck pulled these hills with no problems, but the logging truckers knows this route and they like go at 75mph. I traveled at 60mph and heard one of them saying that I slowed him on the down slope, but pulled away on the up. So I called back to him and told him to let me know when he wanted to roll-on-by and I'd back it on down.
He was majorly happy and thanked me very much
