A 30 amp plug has one hot wire that feeds your rv while the 50 has two hot wires but the conversion adapter only uses one of the hot wires. There is no benefit to plug in a 30 amp into a 50 amp unless the campsite outlets are damaged.
If your rv has a 50 amp there is a adapter that will let you plug into a 30 amp and 20 amp at the same time this will give you the two hots your camper needs the downsides are.
1. One hot will be fused at 20 while the other is at 30. The rv was designed to have 50 on each of them. Depending on appliances in the rv you might have a voltage drop or tripping breakers.
2. If the 20 and 30 amp breakers are on the same circuit in the campsite panel you could produce a heating factor on the nutural depending on the load, thus causing a fire hazard.
