Although this wouldn't give them the theoretical 100 amps (50 amps per leg x 2 hot legs) available from correctly wired 50 amp service, it would give them a theoretical 50 amps (30 amps on L1 + 20 amps on L2) - more than available from simply adapting down and plugging into the 30 amp plug. This practice doesn't work with newer GFCI-protected 20 amp outlets in the pedestal since the 50 amp rigs have a common neutral, and the neutral leg current on the 20 amp outlet doesn't match the hot leg current - therefore, the GFCI will trip when a cheater box is used.

Some campgrounds responded with the one outlet policy. Others simply forbid the "cheater boxes".

Although I have not come across that I can see where it would come into play especially if the site had an upcharge for 50 amp and the Rv'er was too cheap to pay it and/or a 50 amp site was available. It that case the site owner should ask the Rv'er to depart the area and never return.
