Oh, I believe that, too.
The biggest issue with my '15 HD was the damn mag chloride, and calcium chloride used on the roads. I did not do enough to keep it clean in the winter, and it was rotting from the bottom up.
The 2nd issue was the paint. I would leave it for 3-4 weeks at a time in our lot at work, no cover of any kind. The UV finally got to it, and the paint was peeling off. Some places had 6" strips gone.
There were a couple of other "issues" that made me want to get rid of it, nothing major, but the cost of putting it all back in clean shape far outweighed desire since we just rarely towed heavy any longer.
Mechanically, it was a great rig. MY NEGLECT of the body/exterior happened slowly, and I was traveling so much in my work truck that I just missed it.
I was fortunate that the market for that used truck was strong, and I could not pass up the deal I was offered.
I will take good care of little half ton
The 420 HP/640 TQ is there if we want to drag another trailer.
Loving the Active Exhaust mode! May not even have to buy exhaust
