New owner of a used 2015 viking VI

Hey guys, I've recently acquired a used viking. I haven't ridden it much since I picked it up last week, but I will be servicing it soon & then it will be enjoyed often. It is a 2015 model & the original owner is a family friend, so I know the background. Any information y'all have on what I need to service, replace or take a look at would be greatly appreciated. Thanks!
