Do dealers even order regular or extended CAB's anymore?

What GM didn't make when I bought my truck, and after just checking the web still doesn't, is a 3500 double (extended) cab with the 6' bed. They do in the 2500 but for the 1 ton if you want a short bed you must get the crew cab, or if you want an extended cab you must get the 8' bed. Or do what I did and get the 2500, beef up the tires/wheels and suspension and get one of the lighter campers.
