Grizzly,
Being in Albuquerque, I'm amazed that you don't see what we see here in Houston. I can drive about 1 mile from my office to a local Ford dealer and pick from probably half a dozen or more F-450s and F-550s that are set up for gooseneck towing for the "horsey crowd". These are typically crew cabs with leather, etc. and a custom towing bed, and they sticker out in the low to mid $60K range the last time I checked. They sell a decent number of them here in the Houston area. Within the last year or so, the GM dealers have decided to compete with Kodiak models set up for horsey or RV towing service.
Go through just about any RV park and you'll see lots of 5th wheels (including mine) that are really too heavy for 1-ton duallies. The tendency is for (1. ) 5th wheels to get longer and heavier with as many as 5 slideouts available today and (2. ) more and more RVs to be sold as the Baby Boomers hit their peak earning and/or retirement years.
Between the "horsey" and RV crowds, there's a market for tow vehicles larger than the Ram 3500 dually but smaller than the FL-60 or FL-70 Sportchassis. Right now, Dodge has chosen to ignore the truck market for anything larger than a 3500. By doing so, they are making a conscious choice to abdicate this market to Ford and GM. That's their choice, but when replacement time comes around, I
will be voting with my checkbook!
