Do you want convenience or opportunity? I like my cable with the evening news and weather, I like the microwave, I like the air conditioning etc. but I am willing to forgo all of that for a couple of days in the woods and being limited to battery power if the opportunity is right.
With the battery set up that came with my TT, I will go about three days on the battery but it is just my wife and I. If I were planning on an extended stay or frequent boondock trips we would have to improve on our electrical resources.
I am not a fan of generators but I am in the minority on that issue. Most of our travel is camp for a few days and see the sights then move on; so an occasional non-electric site is not an issue.
