it's totally safe
It's exactly what happens when you use 30 male to 50 female to run the 50 amp RV on a 30 amp service
Only the so called cheater pedestal, would be one 50 amp leg, ( instead of only 30 amps ) powering the 50 amp outlet, giving 25 amps on each leg
Or 50 on one leg or whatever each leg of the RV pulled up to the total of 50 amps of 120v available
How safe it would be depends on how the electrician wired it. If both legs of the 50 amp breaker are connected to the input wiring, it is possible to draw 50 amps on EACH leg in the RV. Instead of the neutral carrying the difference between the two hots, it would carry the sum. 50 + 50 is 100 amps on the unfused neutral. Unless it is oversized, that could be a problem. While it is not likely an RV would draw a full 50 amps on each leg, it is technically possible.
