Consignment...Seller won't budge off of asking price.

I haven't bought a consignment RV before, but I have bought a lot of used stuff, from S&B houses to old tshirts :).

Some people will dicker and some won't. Those that won't might not know it's a thing, and that they should set their asking price higher. Or they might have philosophical objections.

It doesn't matter: This is the price. Do you want the rig? Can you get something you like as much for less, or is this the one?
