I'm not 100% sure there is any such thing as MSRP for Campers, at least as you would think of when shopping for a car or truck.
Somebody correct me if I'm wrong.
In my own experience, I looked at dealers, and at various online sites. For my exact camper (and same options) I found no fewer than 4 different "MSRP" prices. I think it may have been more like 6...
Now, I was able to get a decent idea of "MSRP" from this research, but officially, I do not believe there is any such thing - again, as you'd think of it when car shopping.
Edit to add:
I think the only way to know for sure it to ask the dealer to show you the factory invoice, not the build or option sheet, but a real invoice.
