My Prius camper- a mini hotel on wheels!

Nice setup!

I would suggest moving the + connection for the inverter from the bolt where you have attached it, just to the nearby bolt that is on the other side of the battery fuse. (It's behind a little spot where the plastic of that fuse/connector housing folds out.)



Here's what that looked like in my old Gen 1 (where the same style fuse/connector housing was used). The cover flap is folded open in the photo so you can see the connection.



Connecting at that recommended spot means you've got the battery fuse between your inverter wiring and the battery, and also, at the far forward end under the hood, the DC/DC converter fuse between your wiring and the car's converter. That makes it a well-protected spot.

It also means that when you are running the inverter and the car is READY (which I hope is pretty much always, right?), because your inverter's power is coming from the DC/DC converter then and not from the battery, you just have the voltage drop of one fuse on that power path, rather than two.
