X2 on having the adapter.
One RV park we stayed at last year had the four electric hookups for four sites in a central location at the rear. We didn't know that 2 pedestals had 30amp only and 2 had 50amp only, but saw two trailers plugged in so we backed in and started setting up. THEN we realized the two remaining pedestals were 50amp only.
DW made a LONG, hot walk to the office. They loaned us an adapter for our stay.
We bought an adapter so now we have one 'just in case.'
