"Some of our camping trips may involve boondocking"
"Some" and "May"; these are the key words. So my question is, how much money are you willing to throw at the "some" and "may" problem? That will determine the answer to your question. If the key words were "all" and "will" you could very well come up with a very different answer.
I have had a camper for over 15 years, I have never used a generator or solar. Only three of the camping trips in the camper involved dry camping for more than a day. In all of those instances I was able to survive for a week on just the batteries by being a minimalist. All other times we had electric. I just don't see solar or a generator in my foreseeable future. The "some" and "may" just don't add up for me.
