If u have a greater need for power you can get a Jackery 1000 or 1500 enough to run all your appliances except AC. for hrs on by connecting the shore power cord via a dog bone 110 adapter for entire rv. You can solar charge, using gen or cig lighter also and have endless power for boone docking. Less complicated and significantly cheaper option and can also use at home for power outages.

That's not a battery - it's a power station, sometimes called a "solar generator" because the small lithium battery can be charged by an external solar panel with its built-in MPPT controller. The inverter part is only 500 watts. It is currently listed for $500 on Amazon but you can apply a $80 coupon to bring it down to $420.
It may work for you but most RVers would want that inverter running from their house batteries and not have to run extension cords to the TVs.
