Looks good!! When I put the addition on our house last year (master bedroom/bathroom and 3 car garage) I had the electrician put a 30 amp RV outlet on the north side of the garage, where I also had a 16' wide concrete slab poured for parking the camper. But I had him run 8/3 wire (left the red disconnected at both ends) just in case we ever get a camper that requires 50 amp I can easily make the upgrade by just swapping the breaker and plug.
