[chip46wis]

I am in need of input here.I have always bought/sold 1/2 tons and today a friend called with a lead on a 1971 original camper special 3/4 2wd 396/402 102,000 actual miles -auto and he said in great cond--opinions are always different I know.Truck is a original Texas truck and been in storage since coming to Wis 18 years ago in a heated clean dry shop.NO rust anywhere.
I dont see many out there to compare to but it seems the ---average--- value is a lot less on a 3/4. owner is firm on $6000---Input? ty
