It's low miles but has serious body issues. Namely, the door bottoms and cab corners rusting is a HUGE turn off for potential truck buyers in my experience.
It's also RWD vs. 4x4, auto (some prefer this, but many do not), 305 vs. an old 350, manual windows and locks, it's that wrong kind of year where it's not vintage, radio needs upgraded desperately, and electrical "wackyness".
Again, just my opinion, but those are BIG turnoffs for MOST looking at older trucks. If this were put on the FB marketplace or CL I could see it bringing $1000-1200. I'm not saying what it is or isn't worth, I would just be surprised if you're able to get more than $1200 for it. My 1998 F150 had just one small patch of surface rust, was an ext cab 4x4, had power everything, had no mechanical or electrical issues, and it sold for $1800.
Best of luck man.
