Has never been driven in winter but has unfortunately set outside that's were the rust on the rockers comes from the truck starts right up would be a good resto project has body rust needs cleaning and gone threw will need tires they do have some dry rot the flat bed was hand made and is very heavy duty and well built the frame and underside of the truck is in good condition it has a custom made gas tank I believe it's 40 gal
