At least one manufacturer increased the margins on the MSRP to over 50% nearer 60%.
When they say they are losing money on every unit they sell, offer to lock the doors for them.
Yes I would shoot for 50% to 55% off even 60% as any unit unsold cost them money on floor plan interest. Those buying RVs may be in better financial situations than many still working...most have to watch the budget and budgets are shrinking as Retirements took a very serious hit. Sales are way down now, and they want to move inventory. They will try to get the most out of a Consuemr as they can. If you feel like you are not going to get the deal you wnt, take the figures they give you and shop and bluff. Line up financing first if you can that is a letter of credit in the old days. Offer them 50% and no more and tell them you are ready to write the check t your price.
