I run and recharge all my gear off 12 Volts even when in a Park connected to 240. However I do carry a small Dick Smith Inverter that I can use on 240 but that is more if the 12 Volt power pack for the lappy blows up or I only have a 240 Volt charging option for the item of equipment... so technically, I am still on 12 Volts I spose.
The 7000 has no probs running all our needs IE Engel, Lighting, Water Pump, Lappy and the Camper House batteries (twin 105 AH Full River) are always fully charged. All that happens is if the lights and lappy are on, the frig is running and we hit the water pump (7 amps) then we are momentarily drawing on battery for a few seconds to fill the kettle or maybe 10 seconds for the washing up.
I would consider a 15000 necessary pretty much only if you are bush for a while, your House Battery is heavily discharged and you will only be on 240Volts for a night or so and then heading bush again so you need to recharge the House Battery as quickly as possible.
