Cost could come from many things. Do they use a high grade of stainless steel? Or is it just chromed A36? How is it put together? Machine welded? Or crimped? Do they have several different designs or just one or two? The manufacturing process comes into play. How big is the company? Do they have other products to provide overhead for? All sorts of reasons.
Bottom line is, are you happy with it, and would you have done anything differently? Looks good on the truck! Do it for you because you like it!
