Question:
Many people ask what is the power panel like at campgrounds?
What side of my trailer should I have power come into when I
make my inlet connection?
Answer:
See what the power panels at campgrounds look like here
Campgrounds have 15- 20 amp, which is the standard household plug. they also have 30 amp, and a 50 amp twist lock, all 110-120 Volt. With an A/C installed (5000 btu) most trailers are not going to pull more than 15 - 20 amps. Unless you really load up on the electrical side. I just would not cheap out on the shore power cord.
1) 15-20 Amp 110-120V
2) 30 Amp 110-120V
3) 50 Amp 110-120V
End:

Simply put, one can't air condition a trailer using batteries. Even a small window unit draws 10 amps on ac current which would be about 100 amps dc current. You'd have to have about 1000# of batteries to be successful and then you'd have to figure out how you're gonna charge 1000# of batteries each day. Gonna take a heck of a battery charger or solar system to do so.

Minor nit.. none of the outlets shown are "twist lock", and you are unlikely to run across locking connectors on a campsite pedestal. Also the voltage rating on the 50A connector shown above is wrong. It should be 120/240v, as it is a 4 pole connector, carrying both 120 and 240 volts.
Some types of twist-lock connectors, such as the L5-30, are used for RV power inlets, with the other end frequently being a non-locking type (such as a TT-30P) for compatibility with the pedestal. Adapters are available in both directions, for applications such as connections to portable generators using L5-30R, or if you wish to use locking connectors throughout the entire cable run, and adapt at the pedestal as needed.
What are actually shown:
1) NEMA 5-20R (120v 2 wire grounding 20A) (your common household type outlet)
2) NEMA TT-30R (120v 2 wire grounding 30A) This outlet type is used only for RV hookups, hence the Travel Trailer (TT) designation. (Note that this is not a NEMA 5-30R, which has the same voltage rating, but a different physical configuration.)
3) NEMA 14-50R (120/240v 3 wire grounding 50A) (also used for electric ranges in new installations, replacing the old 10-50R, which was a non-grounding type.)
