My wife and I have an RV that is part of our emergency preparedness plan because my home is in a flood zone; if it floods, our RV is ready. All we have to do is turn the key and go.
We also plan to use it if we lose power. If it’s cold outside no problem, it has a propane heating system. Need to cook, go to the bathroom, take a shower, no problem. RV’s are self-contain living units that fit the bill perfectly for certain types of disasters.
Having a good generator, solar panels, batteries, and composting toilet can extend your time off-grid; many people live like this full time, but RV’s do have their limits, and bigger is not better in my opinion.
If you’re going mobile during a large-scale disaster, maneuverability will be important. Abandoned cars could block your way, and you may find yourself in a tight situation you need to get out of quick.
Fuel is another concern because you will have to carry enough of it to get to your destination. You will not be able to count on gas stations, so good gas mileage is crucial.
Others problems you may face:
Your RV will be a target if there‘s civil unrest. Looters will see no difference between your stick built and mobile home, and trying to defend it from the inside would be foolish. Bullets will penetrate those thin walls like butter.
You could have an engine failure. If your RV dies on the highway, you may need to head out on foot in an unfamiliar area.
So in closing, I would just like to say, while RV’s have their limits, they can be awesome bug-out-vehicles; for example, a lot of people evacuated to a campground near me this hurricane season, proving that RV’s are great for vacations, and evac-ations as well.
As always, this is just my opinion.
