I'm not sure if your post has a typo? You say 2008? but both the units in your link are listed as 2018. I have a 2017 372 rd that I bought new last spring.
It is a Wildwood Heritage glen. They added the ltz for this year. Don't know what that means. I saw a 372rd at the rv show this spring and the only differences between mine was
1. they added the moryride folding step
2. they added slam latch baggage doors to the under front storage unit instead of the cheap turn keys.
oh forgot one. the unit went from a creamy yellow color to white
