Hey TxDoc, this isn't related to the recall, but I was just looking at your truck and noticed you had the GMC mud flaps. I would highly recommend removing these and ensuring they are not coming in contact with the paint (and thus removing it).
I had these as a *STOCK* accessory on my '01 C3. After having left them on for about 10k miles, I decided to take them off and found they had done very noticable damage to the paint. Someone else here experienced the same thing with these mudflaps.
By the way, that's a nice looking truck!
