Onetype, Howdy;
If I were only about 40 years younger ...
You mentioned that you sometimes travel to outlying parts of your State to do your job.
In those instances do you plan to stay at an RV Park or on site and do what is referred
to as Boondocking? Some RV Parks won't let you stay unless you are fully contained and
some will. Depends on the owner's whim. If you choose to Boondock then you will find
having 12vdc a very handy thing to have already installed. It's also comforting to be able
to have lights and some essentials powered when the power goes off due to Mother Nature.
