Hi Andrea, I have fitted the Kathrein fully automatic system to my van and my friends van with no problems ,but due to the weight and stress from the wind when it is raised it needs to be fitted to a very stable area of the roof, my van has the full size fridge in a floor to ceiling cupboard ,the dish is mounted directly above and fastened down into the cupboard framework making it very stable, I have had this system for 18 months and have had no problems at all ,its great you just pull up on site connect to EHU and swithch on and it goes up and locates sat while your setting up so when you sit down for a cupper tv is up and running
