I always try to remember that some RV'ers are weekend warriors, or vacation week(s) travelers. Others are out for months at a time, or full time.
A month at a time, or full timer, may have a different set of needs then those that are out for shorter periods. (Keeping computers up; wifi and cell phone boosters; extra freezers; possibly medical equipment needs; etc.)
I generally agree with the comments about following the campgrounds rules. I personally ignore some of the 'glances and shakes of heads' that I've seen while other campers are perhaps walking by... I've had a few times where people make comments like 'Why come here to just run your generator?', and worse... I consider the source, and suggest they have a good day.
Sure, do what you feel is prudent as far as augmenting your equipment arsenal. We have 800AH of battery bank, and 1200W of Solar Panels - but when your deep in a forrest, generators are still required to augment... I never apologize for following the rules
! Twogypsies, and others, have passed on some ideas on reducing power consumption.
If you are running a portable generator. Get one of the quieter models upfront. Not just for 'those around you', but also 'for yourself' too... Look at some of the mod's available to even reduce those low sounds even more. Like ice chest's modified to hold the generator, and even more muffle the sounds.
And, if you have the space - two 6V deep cycle batteries will support you better then one 12V battery (which quite often, or not true deep cycles batteries). Trojan T-105, 125 or 145 (Have to go look some, has not heard of the T-135 so they must have new models.) If spending the money to add two 6V's, and really want to maximize capacity, and add perhaps some reserve for contingency, spend the extra coin up front for battery compartment modifications of the hight capacity batteries. 9 time out of 10, it's a matter of head space, with same foot print that a smaller capacity battery will take. And cables are going to usually cost about the same for standard Golf Cart 6V, vs say higher capacity 6V's.
And read up on the Boon Docking sections for other tips to get by with less power, water needs...
But go have some fun, and as long as you follow the rules - forget about it
