Safe 80% discharge is a BS for sure. Otherwise, get a pair of those GC and a 3-day trip with a generator is not really that "long".
Yes, people are running gennies in a Walmart lot while running the sat receiver and AC - if this is what you want. I think you don't even need an RV if those big plans "to see the world" mean seeing it through the TV screen :)
When you do start long trips, you will find that AC is needed less than you think. Summer in Canada is one thing, and snowbirding in the South is another. 12V fans like Fan-Tastic will do most of the time. Long trips further South than the US would require a bit more than adding a fan though. You may read blogs on Mexico and S.A. Essentially, those rigs are self-contained in the way unknown to people who travel a day or two in Canada or US. Solar, small compressor fridge that needs no propane, and other things.

I don't carry a generator.
Another proof to what I've found long time ago - people carry generators because they want to. The only device that is necessary AND can't be powered off the batteries and/or solar is AC, and only when it's really hot. Everything else can be modified to work off 12V.
