One snag might be the pricing on 3 year old C's. I never see them at prices I like. If asking prices are accurate, I could get almost as much now for our 2014 as I paid for it. It was the same situation when we were in the market. It didn't make any sense to buy late model because they were almost the price of new. But we bought right by using a price from RVdirect.com to negotiate with dealers closer to home.
I think most people pay quite a bit more, and that keeps the resale up on late models. My suggestion is to get a price from RVdirect, apply 3 years worth of depreciation to that number, then see if you can find something. I guess 3 years of depreciation should total 25-30 percent?
