Having just gone through this process, go with the Magnum or Victron hybrid inverter/chargers. They are state-of-the art. They both can provide power to most* of your trailers 120v needs and have intelligent four-stage charging. You will need to have a good AGM or lithium battery bank, but if you are upgrading batteries anyway, it is worth the cost.
*The AGM batteries cannot power your A/C (but the right size lithiums can).
