I too would suggest the 13.5K BTU, however the size of your RV comes into play.
I looked at the RV size and stick with my suggestion.
Remember that an A/C too large isn't as effective as the proper size one.
Your Generator will also thank you and as someone mentioned you can use a 15 amp circuit when at home. Just make sure the circuit is dedicated for the RV and doesn't have other house stuff plugged inside the home.
Happy travels.
EDIT------Unless the unit comes with a heat strip in the A/C I would never pay extra for it.
