My wife..........who is not experienced pulling any trailer, and hasn't driven this diesel yet at all.........is in back seat with grandson in his car seat. We go down the 6% grade out of Chattanooga. The truck downshifts, I assume to about 3rd, and RPM's rev up. She gets nervous and says "WHAT'S that sound???"......
I still have to tap the brake though. I try to hit brake till it smooths out, then let go. I have a laser heat gun and the brakes haven't gotten over 135 when I've stopped (assuming I'm aiming gun right, and assuming 135 is 'normal').
