Installing a 120V-30amps outlet
I want to install a 120v-30amp RV receptacle on the outside wall of my vinyl covered garage. I've read on how to wire it, and understand that well. I would like to know what kind of weather proof box...

Don't screw around. Install something similar to the RVU75C listed on rvpoweroutlet.com. Where you buy it does not matter to me I am just using them for an example. If you do it this way you will be set for any future upgrade you may make. Since the box is wired inside all you have to do is run your 6 or 8/3 NM from a 50 or 60A breaker in your main panel, mount your box and plug in. It is quick easy and you will be happier in the long run.

/\ The circuit breaker at the box is important for saving your plug. You should use the circuit breaker to disconnect before removing the plug, and turn it off before plugging in, then turn the circuit breaker on. Circuit breaker points are designed for it, your plug prongs and female terminal are not, and will get burned over time, connecting and disconnecting to a hot circuit. Let the circuit breaker points bear the load.
You DO realize that YOUR TRAILER HAS A MAIN CIRCUIT BREAKER FOR THE SHORE CORD built in?
So really a dedicated breaker at the RV30A outlet is not all that necessary as long as you always remember to turn the MAIN breaker in the trailer off each time BEFORE you disconnect.
The only reason I put a breaker near my RV outlet was for the fact that I wanted to add and a 20A outlet to the same box. I use the 20A outlet/circuit to run a hedge trimmer, power tools plus a dusk to dawn yard light. Cuts down on dragging 100ft of 12ga extension cord around the yard to reach things..
So, I ran ONE run of 10ga wire into a small breaker panel and in the breaker panel I have one 30A breaker for the trailer and one 20A breaker for the 20A outlet.. I didn't want to power the 20A outlet directly with 30A from the house and I had the breaker panel and breakers laying around..
By the way, pretty much all home type breakers ARE NOT RATED for "switching" use.. In other words using a breaker like a light switch WILL cause premature failure of said breaker. 20A and 30A breakers are not all that expensive at $7-$10 but 50A double pole breakers start to get pricy..
