50A RVs connections, per the NEC, are permitted to be either 120/208V or 120/240V. RVs should (and generally are) designed and built to work properly with 208V between the legs. Even if there are 240V devices, usually they're just heating elements that work fine at 208V...indeed, most electric ranges, water heaters, etc. are labeled for both voltages, as apartment buildings and such are not infrequently wired with 120/208V three phase power.
In short, you shouldn't have any problems, and I doubt there would be any concerns with the agency having jurisdiction assuming the wiring is done properly to standard by qualified people. (That, of course, generally means by a certified electrician.)
