I second the fridge. Best purchase we made. There is a learning curve. Remember it's not ice. Don't pack the fridge with drinks. Stock it with a few and replace them as you use them.
I'm not big on having all my solar mounted. Reason being I like the trailer in the shade so it stays cooler, more comfortable and the fridge has to run less. If you solar is mounted on the trailer it won't be in the sun. Use quick disconnect plug wired to the battery and the panels. And yes my batteries are in the front also.
We use our inverter for charging laptops and camera batteries. That's about it. Never used shore power. Hopefully I'm never that close to a plug.
Good luck you'll love the trailer.
