I'd guess that if you are shopping for new, the manufacturers aren't going to lower their MSRPs. Paying above invoice is hopefully going to end, though.
The used market appears to be poised for a major correction though....probably already is.
I've been watching stuff like this in BAT......using Sprinters as a measuring stick:
2021 Mercedes-Benz Sprinter 2500 4×4 Camper for sale on BaT Auctions - ending December 23 (Lot #94,211) | Bring a Trailer
Probably going to end up at $120k....reserve not met; (that is my guess).
This is effectively a brand new Sprinter Camper van that 1-year ago would have fetched $140-180k easily.
Unfortunately, not all owners are ready to except the new market. If you look through the last 6 months at Sprinter based campers at BaT, 4 have not met their reserve...only 2 have sold.
A lot of folks paid $200k for a new build on a Sprinter and are hoping to exit the market without normal depreciation.
EDIT: BAT Auction sold for $128k, reserve was $125k.
