If you want to stay with Vättern as your nearest neighbor, it is at the Vätterstranden Huskvarna RV parking that you should park your camper for one night or more.
On the border between Huskvarna and Jönköping, you will find this site just off Vättern's beach. From here you can easily take your bike to Elmia and the fairground area there and from there continue your journey on the bike path towards Jönköping city. From the park, it is walking distance to Huskvarna center where there are grocery stores. On the park, there is access to drain gray water. During 2020, there will be a temporary toilet, but there will be a permanent one shortly.
