At the end of the day what you have with 50 amp RV service or conventional 240V service is two legs of 120V each, a neutral, and a ground. How you break that out to different connections is determined by what fits your needs.
You don't mention about any power inlets you have but the assumed 30 amp RV power inlet of either an attached cord or an exterior plate mount inlet. If you establish either a cord or plate inlet for the new 120V A/C service, you will want to split the 240V service and connect appropriate connection to that service. Sometimes, this is most elegantly done by building a breakout box that has either a 30 amp outlet and 15 amp outlet (two receptacles) or passing through one leg of the 50 amp service and having a single 15 amp receptacle.
An alternative to a break out of the 240V service is to connect with the traditional 30 amp cord and have an additional 120V cord to the pedestal as most campground pedestals have both.
