Lucky! My daughter towed two horses on the 1 7/8" ball during a fire evacuation.... When the trailer was a 2 5/16"!!! Nothing happened, I just noticed it later when removing the ball mount. Could have been U.G.L.Y.
I've got 11,000 mi on my 6.7 and I've never noticed a single regen occurring nor has the truck shown any warning or other indication of a regen. I know they are happening because I check my DPF filter gauge from time to time. Why isn't my truck providing a notification of a regen?
