Polar package was/is a $1.50 worth of reflectix underneath so don't try to use it it Sub zero temps, Pacific package most likely means it was assembled in Oregon & Anniversary edition just added more to their made up price with a cute name. I would doubt that there's any model of RV that's been on the market for 20 years, most models are lucky to last 20 months before dropped or changed.
My point is most of the catchy package names don't do much to add a lot of value to a RV, but sound impressive to potential buyers.
