Eh be patient. He may not live on the property where the truck is.
I'd be asking 1000 for my 78 f150, if I were selling it. It's in much worse shape.. the doors and hood are the only straight body panels on it. That dent on the bed is from the top of an 80ft tall cottonwood falling on it. It also hit the cab. It also had a superduty slide into it in the ice once, which was followed by an explorer into the superduty. It was a Ford sandwich Haha. And it's been sitting for 15 years. It's got a 351m, np435, np205, and a factory LS 9" under 3/4 ton rear suspension. The axles are rusted solid. Some day I'll build it up.
