Question on wire size for 30a
I need to install a 30a RV outlet on the side of our house for our trailer. I need to go about 60 feet from the panel. Would 10/2 Romex be sufficient, or should I go bigger?

#8 Type NM normally is three conductor with ground.
If this is all inside the house, you may just install 10/2 with ground and live with it. You will most likely never come close to a full 30 amp load.
You would just need to watch using heavy items like air/cond.
You shouldn't need to "watch" using heavy items. Not every one is going to "watch" and that's how things get burned down. Let enough heavy line carry the load properly, and let the circuit breaker do it's job.
