I would think you are just going to have to actually sell your Class C, print out a floorplan (or close to it) and go to the RV places and talk to a sales person and just try to get the best deal you can. If you know what you want to pay, just do some talking and old-fashioned bargaining and see what they can do for you. I do know the MSRP is never what you want to pay for it. And watch for sales, be a little flexible and you may actually find a used one that maybe somebody used very little and you can get it for a good price and in your budget.
