All depends. Rare... some are. Desirable, well that also depends. If you want a bigger truck with a HD chassis then look at a Longhorn. It was built on a 133" wb one ton chassis and sprung as either a 3/4 or 1 ton. Fleetside wood beds only. Many lived most of their lives under a camper and have typical camper mods. Aux fuel tanks are very often found. Equipment levels run from stripper 6cyl/3ottt to Cheyenne Supers with about everything. Values run similar to the more regular truck models, but there is a lot smaller market for them. What are you looking at? Lowest production were the '68 C/30s the best were probably the '71-72 mid to high end optioned trucks. More info is just a request away.....
