We had an RV for years……..they are made to resist 70 mph winds
The only bad time we had was in New Mexico camping in a wide open space….
..a huge storm came up and our RV rocked and rolled but held fast!
In a storm be sure and pull your slides in if you have any.
Lower your antenna….
…and don’t park under trees where limbs can hit your vehicle
Also, see if this campground has a well built ( concrete block) building in worse case scenario
Thank you kindly, Guenevere.
