Does the blocked list allow for wild cards so you could do *nomad* ?
It's kinda fun to be on someone's block list. I can tell I've made it when they post the same reply I've already posted on the same thread....sometimes nearly ver batim. :)
Just an observation, a good dealer would know why the configuration you are trying to set up comes up that way and would be able to tell you what is missing to obtain the 11.5K or what you chose to lower it.
NADA is not fair pricing. It is highly inflated and about as bad as so called MSRP pricing on RV's. I would start with a cash offer much lower than asking price and see where it goes. Be prepared to walk away.
Your current vehicle will be problematic IMO. I can appreciate the minimalist approach but living in a tiny box for extended periods of time creates its own set of problems. A truck will give you more flexibility and options.
