Ran my 13 5.0 f150 pulling the same loads to 190k. Then it started to miss at idle and found #4 exhaust valve burnt.
Sent it off to auction where it hammered for 7500 bucks (paid 23k when it had 65k)
All in all it was a great truck and I was not nice to it. It worked for my money.
When I had to trade out my company truck I decided to buy it.
I flipped it and made $4009 for doing nothing. Even though I can use my company truck for personal use, I really should have kept that one.
