The 'permanent' fix is to repair/replace items damaged by the the storm, the same as everyone does after a major wind event like a hurricane.
There is no way to prevent the same from happening in the future in a similar event. No part of any RV is built to withstand 130mph wind! Move it or lose it.
Replace the flimsy OEM vent covers with after market. Most will be at least double the thickness and durability.
Then add an additional vent cover like MaxxAir or MaxxAir II. Not only do they provide extra protection, but allow you to leave the standard vent cover open during travel and rain for ventilation.
