Promobil compared the all-season caravans Adria Alpina 663 HT and Knaus Nordwind 660 PXB. The models' similarity is attributed to a senior manager's move from Slovenia to Bavaria and the Alpina's strong test results. Both caravans feature Alde C 3020 water heating and underfloor heating, but differ in body construction: the Nordwind uses aluminium, polystyrene and wooden battens, while the Alpina uses GRP, XPS and PU profiles. The Alpina's base price is 48,190 euros, the Nordwind's is 49,900 euros. Adria offers six floorplans, Knaus three.
