Wander King

Wander King is a brand of motor home.

History
When the New England RV-er parks his RV in Homer's backyard, Marge looked out the second story window of their house and angrily asked Homer what they were doing here. Homer told Marge that the RV-ers were his new friends. The New England RV-er then asked Marge if she was driving "one of them two-level Wander Kings", apparently thinking that Marge's house was a large motor home.
