Very nice solution. While not the answer to everything that can happen, as an engineer I think in terms of statistics. So, statistically speaking, the chance of having to drive through a post-apocalyptic war zone and being shot at or roving mobs is just shy of zilch (though admittedly those odds are looking more probable every day). Again, statistically speaking, you will almost certainly deal with storms (winter/cold and summer/hot), evacuations if you live is wildfire or hurricane areas, and the obvious things like camping for pleasure. Given those statistics I think your solution is a very effective one and trying to maximize your ability to weather those things that are most likely to occur is a very realistic approach to survival (at least to me).
I also bought an old truck-camper a few months ago and am converting it to be more BO/BOV friendly. For the sake of sharing ideas, here are some of the things I am doing with mine. They might be useful to you, maybe not. *Removing toilet and adding a compost-style toilet so that I don't need to worry about water for it or gray/black water storage. *Switching everything I can to 12V and lighting to LED to minimize power consumption and eliminate need for a generator. (I also have some solar panels that will go on it.) *Removing refrigerator and adding 12V cooler. *Removing stove/oven to make more room for storage and using single burner LP for indoor cooking. *Adding a handgun safe that is bolted such to make it as difficult as possible to remove. *Stocking it for long term camping as that is largely what I will be doing either for pleasure or for BO purposes. *Replacing some windows with windows that are more like home-style windows and more efficient, and adding a layer of plexiglass to others and sealing them for efficiency as well. *Lastly, I'm going to add 1/2 foam board over the existing walls/ceiling and then cover with paneling so it looks "newer" and is better insulated.
Perhaps that will give some more ideas to you. Great thread. Keep up the good work BuggingOutMan. Don't let anyone discourage you. Your choice of BO solutions will be very used and enjoyed even if civilization remains civil.
