Hmmm, virtually all the RVs I have seen (except the celebrity calibre busses) utilize 120 volt AC units. The RVs that are 120/240- 30A-50A simply use both legs separately to power all of the loads, including the AC units which are 120, . This way they can still use at least one of the AC units when only 30A is availabble.

Here in Arizona everyone wants a 30 amp hookup for storage so they can run the AC when loading/unloading and cleaning.
