Just joined and was checking out this site, pretty neat. Reason for lurking around here is that I just purchased a 69 C30 dually with original 74000 miles. Dont really know why but have always like this style and I have not seen very many duallys. I guess my question is, are these very rare? Mine has a 157 wheelbase, color white, trim green, 350, DR wheels, tinted glass, power steering and brakes. It does need some TLC but is fairly solid. I do believe the miles are correct. Also it does not have a box, I plan on a flatbed but have lots to do before that. It spent most of its life with a camper on it. This is a project for me and my 10 year old son. Thanks I am enjoying reading all the posts on here. I can tell I will learn a lot.
