Picking up my first caravan Saturday!

Hi - getting my first Touring van Saturday after 10 years owning a static in Little Haven Pembrokeshire. Purchasing a Dethleff Rally Nomad 550L from Davan in WsM. Any thoughts, it seems a very neat bit of kit, well planned & in great condition. Decent price too! Off to a CL in Aust, S Glos saturday & then Slimbridge next weekend to try it out. Any thoughts on protective whole van covers for the Winter?? Simon & Louise (the boss)
