Opinions needed!!! '78 Dodge Ramcharger. Should I buy it???

Looks decent, but that thing is probably a huge gas hog. I wonder if it is a fulltime 4x4 model too as the majority of the '78 trucks I have seen are fulltime 4x4. It'd make a cool baja truck though, thats for sure.

And yes, its like that. Ramcharger = Blazer; D150 = 1500 chevy truck ; W150 = 1500 4x4 truck.
