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?

Number eight should work OK.
I would suggest getting a digital plug in volt meter to keep an eye on voltage. Using air conditioning along with microwave could drop voltage down to minimum levels.
I would check voltage at the panel where you are connecting new circuit. make sure it is in the 120+ range. If much below 120, you should think about the #6 wire.
/\This... or just do it once, labor is expensive, and just buy and pull 6 gauge copper. Not worth the risk of voltage drop on expensive equipment like A/Cs or microwaves. Low voltage kills them quickly.
