TimC brings up a valid point. You simply can't rely on "inverted battery power" to operate any RV with the same level of power use that you enjoy while connected to shore power. I suppose you "can" if your wallet is so thick you need a separate trailer to drag that cash behind your trailer, but for most people, that's not only impractical, it's foolish....
Battleborn addressed one aspect of "battery power vs shore power" this way"
For example, a 100 Ah lithium battery will power a typical 15,000 BTU RV AC unit for about 30 minutes. If you’re RVing in hot weather, running your AC for 30 minutes likely won’t do much to increase your comfort. However, if you had a bank of eight 100 Ah batteries, it would run for about four hours.

When you consider that a single battery costs around $1000, then the cost of battery power to run an RV air conditioner for 4 hours would be around $8000. To run it for 8 hours, $16,000. And that doesn't include the cost of the solar system to recharge those batteries....
So, attempting to run a trailer on battery power, for almost everyone, will require some significant "soul searching" to determine exactly what is required, what can be turned off when on battery power and just how hot it can get before we break out the generator to run the air conditioner because we can't justify $30K for a "DC power system and solar system to operate it full time"...
Most people "compromise on resources" when dry camping. Fewer showers (limited water and limited gray tank space), fewer lights, more cooked meals rather than microwaved meals, less TV, no A/C and no fireplace/electric heaters"....
So, take stock on what you "can't live without" and what you "don't need to be comfortable" and make a list of the amount of power you'll use, the amount of money you can spend and then "mesh the two to reach your desired system"... If you can justify that expense, great, but for most, there's a significant cost that can't be justified to even attempt to "dry camp on the weekends with all the electrical equipment we have at home."
