Check this out. This is my 2004 GMC 4x4 Extended cab. 5.3 pulling a trailer loaded with parts for the 68.
Before someone tells me how stupid I am, check the tach. I was doing about 35mph, looked down at the speedo and about sh**. Turns out when I shut the truck off it only drops to about 90. Guess it is time to hit the dealership. Gotta love the extended warranty. I don't know, I thought it was a cool pic.
