WIW..1989 Ramcharger
Talk him down a bit cus why not? IMO those things got expensive but i'd do 3k if it was well optioned/not rusty. between my dad and myself, we've owned about 15 ramchargers... but none in the last 12yrs+ . quarters infront and behind wheel should have been rusted out, that its not is probably because of running boards or it didn't go much in salt cus 2wd open diff?. 2wd w\suregrip absolutely will go through snow. Gas is expensive, and that 35Gallon tank goes some serious miles$. should be an a500 or a518 trans. All our 2wd had 9.25 axle and bvan 350 size front brakes. Yes they make good tow vehicles.
stupid things/negotiate list:
the ECU controlled volt meter is more than likely broke
odometer could be broke (ive had at least 7 that didn't work)
pass seat hinge is broke or tearing
headliner
r-12 AC is also fat chance
typical waterpump/timing chain/front engine seal time/tuneup/trans service/brakes gone trough/flush everything
you'll love the roof vent in the summer.
