It may be a half as** hybrid. I doubt they are doing completely different wiring in the same model. Did they put in a 50amp panel but wire both legs of the panel to the same leg of the 30amp inlet power source (kind of like a 30amp-50amp dog bone connector but internal). That would make for a simple and relatively cheap upgrade. If he needs a whole new breaker panel, that would be a significantly bigger project.
The OP probably needs someone who knows what they are looking at to check out the trailer and if needed make the appropriate changes because 30amp isn't a good plan to run 2 air/con units, even if you can get them to work, expect to burn up power cords if the pedestal breaker doesn't pop.
