You are getting lots of good advice here and you are smart to ask. Here is my 2 cents. There are a few red flags for me concerning the sheet metal. The front metal filler between the bumper and the grill is missing. I wonder why. Could the truck have been hit in the front? The left fender is too far back to align with the front of the hood. Again I would like to know why.
How much bondo is on the truck? Sometimes you can feel the backside of the panels to tell. Look for evidence of rust in the bottom of the cowls, rear cab corners, door bottoms, front and top of rear fenders....
It looks like the holes for original mirrors (on the cowl) have been filled with bolts.
All of these things can be repaired or replaced but nice to know up front what you are getting into.
