Deal ,steal or so so

If it's a 3.9L, I think it's a good deal.

The Dakota came with a 2.5L, four banger.

Do you have, or have access to, the VIN? The eighth digit is the engine size.

P = 2.5L
X = 3.9L
N = 4.7L
Z = 5.9L

Even with a four, it would make a nice DD, as long as you're not looking to haul anything of any weight. My DD is a '95 Mazda B2300, it's fine for driving around, but I wouldn't want to put much in it.
