I think she should ABSOLUTELY expect AT LEAST 20% off MSRP.
IF you can determine the REAL MSRP (many dealers create their own version and try to pass it off as the MSRP), I believe you should be able to get somewhere between 20% and 30% off that figure, ESPECIALLY in today's RV market. Yes, smaller rigs are selling better than bigger ones in most markets, but most dealers and mfgs are still hurting for buyers. If that dealer isn't hurting enough to want to make a sale, find another dealer who is. I would let the dealer know I am definitely ready to buy, throw around some other dealer names where I am also looking, and make him an offer. He can always say no, or come back with a counter. Then you can go from there.
