My Eriba Puck was registered to the first owner in 1975. I bought is off of him in 2009. The kerb weight is 370 kgs, If I add the awning, gas bottle and all standard camping gear it weighs in at around 410 kgs. This tows great behind my mpi estate. cruising at 50-55mph is no problem in 4th gear.
@ Carlos: The same counts for any other vehicle that you drive during your holiday. If your family car is on your driveway every night after work, and it's missing during your holiday that is no different signal than with a caravan or camper.
But my puck is stored inside in a caravan storage. The first onwer had it stored in his garage.
