I would look into a used TC. 2006 or newer Host Tahoe if you want a dry bath or Ranier if a wet bath is ok. Yukon if you want the long one. I would buy a double slide at least for the more open floor plan ... I did, after all. :) You can also consider a Yukon with Tent option. That will give you extra room to sleep.
There are a lot of RVs that are barely used. Spend the money on a new RAM if you are set on a RAM from Dave Smith in Idaho. They come way off the MSRP. At least, talk to them to get a price. I don't think you'll get a deal on a used one.
