We are selling our very well-maintained Adria Alpina 663 HT (white exterior, Urban Greys upholstery), first registered in March 2024. The trailer comes from a non-smoking household, has seen very little use, and is in excellent, nearly like-new condition. When not in use, it is stored in a dry, protected shed on a locked-down property—shielded from wind and weather, and not exposed to prolonged sunlight.

Freshly inspected and ready to go: The TÜV inspection (HU), leak test, and gas test were all performed as recently as April 2026—HU valid through 04/2028. So you can hit the road for the next season right away at no additional cost.

With 6 sleeping spots, a comfortable queen-size bed, a separate shower, Alde hot-water heating, and a winter-ready, heated double floor, it’s ideal for families, long-term campers, and winter campers.
