I finally found what I want at Woodhouse in Blair NE. A 2015 3500 DRW with Aisin tranny 3.73 gears air ride rear suspension, This setup is rated for towing 23500 pounds I think that should do it, better to have more capacity than needed than not enough. It is a Laramie Longhorn with all the bells and wistels more than I needed but what the heck its only money and you cant take it with you.
That was our Senior High School play. I have always lived it, conservatively, but I am not sure there will be anything left to "leave" behind. LOL I am trying to time it so the last penny goes when they pull the plug. Sounds like a great purchase.
