When my dad was in business, we must have had 10 of those Chevy C-10s, K-10s, a '71 Suburban. a '72 Suburban. A squarebody K-5 (ex-police truck) Blazer. and a hand full of Fords. F-250s, F-150s. When he got out of the business, he sold everything through a huge construction auction house. Those trucks would all be worth a fortune today.
