When I had my trailer shed built almost 5 years ago, I had a 30a trailer BUT I installed heavy enough wiring to support 50a should I ever upgrade. We live in north Texas and, although the white-roofed shed helps the trailer stay cooler, I assumed the day would come when I'd need to run both A/C units to cool off 6 grandkids "camping" in my back yard. I ran 50a capable wiring from a new power center to my 30a outlet box and when I bought my current 50a trailer, I merely swapped out the box for a 50a version (see above pic) and I'm good to go.
