That sounds to me like a good plan..
Make sure you use a GFI (earth leakage) breaker that disconnects both active and neutral and install it as far as practical from the DC power panel and wiring (ie. on the opposite side of the cabin if you can). Connect the outlet earth directly to the shorepower inlet earth.
Most of the small AC power panels have an indicating light or similar to show that power is on - a helpful safety feature especially if you don't usually use shorepower - and are pretty easy to mount.
Good luck with your project!
