painted or not that frame 'looks' awesome, no other telltale signs of rust, lines are straight, no bulging around the openings or where the tc skid meets the frame, the torque boxes appear rust free as do the fenders which is consistent with the frame.
In Philly, in 2022, for that price, regardless of the circus going on inside with that dash there's no way I'd automatically write this one off based on the photos alone.
You may get there & see something different that makes it a no-go, but if it's close enough by you've got zero to lose by taking a ride to check it out in person.
As for it being from a dealer, meh, just like a blind squirrel finds a nut from time to time so do dealers.
Edit: & if you want I'll roll with you, pick me up in West Chester on your way
