What winds can a 5 berth caravan withstand

As someone who is living in their first caravan for the last 6 months in Devon in a field on my own, I am a bit unsure as to what is a "safe" windspeed for my caravan to withstand.

Sitting here in 55mph gust winds with the caravan facing as close into the wind as I can get it with my car parked in front but still uncertain as to how much wind is safe.

6Omph forecast for Thurs

Any experience would be apprecitated :-)
