Connecting to a 2000 watt inverter

I’m looking at the classic 400watt system for our 5th wheel. How do most people run power to the 5th wheel for 110 outlets? I was hopping to just plug in the 30amp plug. But it doesn’t look like that’s a option. I know it’s not enough power to run ac but that’s ok. Do most people just run 110 to a few outlets that they want power to for the tv and a couple of kitchen items?

I have two convenience circuits powered by a 300w inverter for small items. I used a small transfer switch for each branch circuit. Need to verify what else is on those circuits to avoid powering the converter or the fridge.

I put the small inverter behind the electric panel. Used the main 12v feed to get power and connected the transfer switches right there. No pulling wire, just make connections.

The problem with this solution is that when you plug in your shore power line, the RVs inverter/charger assumes you are on shore power. So you would get into an energy wasting loop of charging your batteries from your batteries, with conversion losses from DC to AC of 15%, then charging conversion losses from AC to DC of 15%.
Your outlets would have power but you would likely drain your batteries quickly.

What kind of distances and obstacles are between your inverter(s) and the things you want to power? Putting inverters near the batteries makes good sense since the wire sizes are big due to the amperage. Not so big wiring for 120V AC.

Otherwise, powering a few outlets as you suggest or the solutions suggested by @timetoroll are more permanent solutions. Adding a couple new outlets an option too.
