I am the original poster on this thread, and yesterday (Sunday) I stopped by several different dealerships looking at their dullys. When I got to the Ram lot where the guy was touting the air suspension system, I noticed that not one of the 8 or 10 that he had on the lot had it on it. My guess is that it is pretty expensive and not too many are buying it. We hadn't talked cost.
My first Chevrolet was a 1967 Impala that I purchased new (now you know how old I am) and I have driven GM, pickups, suburbans and Tahoes all most 100% since that time. I know, the GMC might be a little more expensive than the Ram, and will tow/haul a few hundred pounds less, but all that I would ever need. I think I am going to make the GMC salesman at least start grinning a little, maybe not smiling yet, but grinning, and start talking seriously with him today or tomorrow.
At my age, this will probably be the last one I will purchase, and I want to feel comfortable with it. Even if it is more expensive, when you take the difference between what you want and the cheapest, and divide it by the number of months you think you will own it (have had my current truck 96 months so far), the extra cost is probably not very much.
I made a mistake of purchasing a trailer with a floor plan that I did not really want because of price, and I am not real happy with it. Not going to do it with the truck.
