When you say,Romex, do you mean solid copper house wire?
Generally RVers tend to believe that solid wire will be more likely to develop cracks, but the wound/stranded electrical cord (like a heavy extension cord) will not crack due to vibrations on the road.
Nearly all commercially produced RVs use standard solid household cable ("Romex") for the AC wiring. Wire breakage doesn't seem to be a big problem. Connections working loose are more common, but would be at least as much a problem with stranded wire (for screw terminals). Stranded wire is also not compatible with the self-contained receptacles used in most RVs.
Most extension cord wire would not be approved for permanent installation per the electric code. That doesn't immediately make it unsafe, but it would make it not acceptable per code in most places.
