Nope, newer rigs run on 240V/50 Amps just like a mini stick house system. Two 120V legs of 50 Amps each. That is provided you're plugged into a real 50 Amp Service. Some CGs advertise 50 Amp Service, but it's just a Single Phase, 120V/50Amp
and the trailer wirinng is sized for two 120v 50A legs, 12KW total. Granted few trailers use 240V, but they could, it's available from the plug. If the outlet is a NEMA 14-50F plug my understanding isthat by NEC code supplying two 120V 50A legs, 180 degrees out of phase, ground and neutral, just like the 240V to a dryer or stove. You'll end up with two 120V hot-neutral legs and a 240V hot-hot if you want it.
