That truck is in fantastic shape for its age!. Body is straight and mostly solid. The wiring in the engine bay is near pristine, so I’m tempted to say the mileage may be correct. If not, it’s still a low mileage truck. I’d jump all over it if it was in Texas! Offer him $5K and don’t budge. $5,500 would be my best offer. These trucks are getting pricey, so don’t expect him to give it away.
Good luck!
