Are you sure these were not 50 Amp outlets? Almost all RVs use TT-30 or NEMA_14-50.

Three connectors: Hot, neutral and ground.

Most RVs are wired for 120V 30 Amp. Large RVs use 240V 50A.

Four connectors: Hot phase x, Hot phase y, neutral and ground.

Most everything around here is wet during the rainy season. And the rainy season is long.

And for the hell of it, 30A/240V "New Style" electric dryer socket, (NEMA 14-30) - 4 holes, one is an 'L' shape :
These are found in some garages. Note that you should never exceed 80% of 'rated' amps, so a max of 24 amp EVSE on this one.

I usually used a 50A site, NEMA 14-50, but a few times those were all taken so I used a 30A site, and it was 240 VAC. Maybe not common, dunno. Only used one at one RV park.
