continental door

Hi
Need help !!! My brother in law is thinking about buying a Freedom Caravan, Not sure if he will enjoy it , the plan is start small and work up !!!
plus he's only got a 1.4 Belingo.
Now the main question !! We have tried ringing a few campsites, and they will Not Allow them on site , because of the continental door ,they say its a Fire Hazard, !! Awning to awning , car side by side, etc .
So just wondering if anyone else has come across the same problem with these vans ???
