1 - 120/240v 50amp
1 - 120v 30amp.

They used the 120/240 50amp feed for the building attached to the trailer, so all that is left is the 120v 30amp. The RV is 120/240, so we just dropped a hot and supplied the RV with 120v 30amp, essentially only running one leg of the RV panel for lights and plugs.

There are no 240v loads in the RV.

I am trying to think of a reason why this would be a bad idea?
 
is this a outbuilding supplied by a single branch circuit (one MWBC ) in accordance with 225.30 and the 250.32(a) exception applies, or is that building supplied by a feeder that serves more than one branch circuit in which case 250.32(a) as well as 225.30 both apply ??
 
It is a separate building built off the RV so we put a 50amp load center in there fed by the 120/240 50amp breaker supplied by campsite, it is a 12 cct load center, feeding lights, plugs and a small hvac.

So all that left them was the 120v 30amp to feed a 120/240v RV

RVs don't have 240V loads. The ones that require 50A/240V have two HVAC units. But the HVAC units are 120V. The 240V is just so they have the ampacity to run both 120V units, plus the other 120V loads.
