Detached shop wiring

Greetings,
Wiring a detached shop/rv garage using a 200 amp sub panel fed with 3 4/0 AL and 1 ea 6ga CU for ground from 400 amp meter panel.

1. I'm putting in a 50,30,20GFCI RV power panel - There will only be one rv plugged in and probably never use the 20 amp outlet as there are already duplex outlets in the area. Basically storage - battery charging and occasional testing of 120v appliances.
Can 50 amp cb and 6-3 be used, or is there a reason to step up to 60 amp cb and 4 ga wire ?

2. All outlets will be GFCI protected, do I need AFCI anywhere ?
Thank You

1. You can do 60A breaker with #6-3 copper. The ampacity of that cable is 55A, and code allows you to round up to next standard breaker size 60A.

2. No AFCI required in a shop.

You are only allowed by the NEC to have one power feed to a detached building so those other existing outlets in the area will need to be fed from this new subpanel. The existing power feed to the detached building will need to be disconnected and abandoned.
