Currently, it is a buyers' market. I would do a nationwide search using RV Trader just to get a feel for what the specific model you are looking for sells for.
The next challenge is to find a good dealer you can work with. Unlike the automotive industry, not all dealers will provide warranty work to a unit they didn't sell.
Even if you are buying a brand-new unit I would highly recommend a third-party inspection. When I was buying my Class C we found two at a dealer. They were nearly identical, except one looked like it was built on a Monday by a relief crew. The other had a much better fit and finish and fewer noticeable issues.
Take your time and do your due diligence. Don't be afraid to walk away if the deal doesn't feel right.
