Not seeing the rip off but do see a potential issue. The gear he is going to get may work for a few slides but it is not going to be the same and not last. His few hours labour will leave him stick at a campground if it makes it that far.
Dealer should have warned of this but very possible an attitude was struck at the counter and they forgot to give this advice. Maybe did not even have the time lol.
Anyway good luck. I could be wrong but have a guy next to me who just read this, his 10 year old citation went through the same thing.
