I am in the market for a truck to replace a 95 Chevy 3500 HD. This truck has a 14' stake bed dump on it. I cannot find on Chevrolets website where a similar truck is still being made. I know they introduced the 4500 but did that totally replace the 3500 cab and chassis option? The 4500 is bigger and more expensive than what I was wanting to put into a replacement for this truck.
