Just bought a 1988 Puck , seems in pretty good condition -- anybody recommend a tow hitch lock or other anti theft device ? Yet to sleep in it but by chance have a tempur mattress topper the exact size so should help as I'm not the best sleeper. Previous owner had substituted the full size gas bottle with the small 3 kilo size which I suppose will be ok but I got to make it more secure . Fridge works fine which surprised me after all this time . We have an awning , a Hypercamp Paradis , like a nissen hut shape , 3m x 3.25 which should be big enough. Towing it with a 1998 Sharan Tdi. Looking forward to our trip to C Brava in 7 weeks . Any hints and tips for a new owner ?
