Get a box with 50, 30 and 20A connections. Use a 50-30 adapter to your trailer this will leave the other leg free when you want to use the 20A service. More is always better when it comes to electric!
If you install the 50/30/20, you won't need the 50-30 adapter. Just plug in to the 30 amp outlet. The 20 amp outlet will still be on the other leg. (On a related note, using the 50-30 adapter on a 50 amp outlet only gives you a 50/50 chance of having the 20 amp outlet on the other leg. The 50/30 adapter taps one of the legs, but you don't know which one.)

If you want to be able to use your air conditioners then go 50. Even though your rig is 30 amp think of the future and the possibility of getting a 50 amp unit. You never know. If you just want to keep the battery charged then do the 30 amp and you will still be able to use your air and lights anyway. All is dependent on how far away it is and what gage wire used.
While I agree with going 50 amp (I am the one who posted the picture of the 50/30/20 pedestal), you don't need the 50 to run your air conditioners. In a 30 amp RV, they will run just fine on a 30 amp outlet.
