A few questions; are you set on this model? Do you plan on selling in the next few years? Are you comfortable with that price?
If you want that floorplan and there are no others available then you have to accept that what's available is what's available.
If you plan on selling in a few years then one year's depreciation may make a difference. If you are going to keep it, then it makes no difference.
The tactic of 30-35% off MSRP was good advice - until this year. COVID has messed up production, supply chains, and the mode of how people travel shifting the balance of RV demand vs supply and has created a seller's market. If a dealer has what you want and it's the only one available then pressing for 35% means the next buyer may snatch it for 25% off MSRP and and you lost the camper you wanted over a few grand. If you find what you want, get a deal you are both happy with and don't sweat 30 vs 35% off MSRP. It's a made up number anyway. Dealers are letting folks walk away from the table because they can. They have low inventory and lots of buyers.
If you can wait and you have to have the latest year, contact a dealer and order one. You may have to wait a while to get it though. And you still may not get the competitive price you would have gotten last year.
If you can wait even longer, then a lot of COVID campers may sell their units once the virus has calmed down - hopefully spring and there may be a surplus of used units on sale. You still may not find the one you want. But makes the depreciation market moot as all campers are going to plummet in value when people start to return to normal modes of travel - if they do.
