What's the proper price range for weight distribution hitch for 16' sports

Hi, there



Was in an AS dealership, and they are selling 2 type of weight distribution hitch. One is asking $995, another is heavy duty around 12xx.



They suggest us buy the $995 one for 16' Sports. I'm thinking it's so strange, why the hitch is so expensive.



I saw some hitches in Amazon only cost around $200-300. Any differences?



Thanks!
