Low Voltage on One 50A Leg
In several campgrounds I've noticed that my 50A legs were "unbalanced". For example, unloaded, L1 at 105V and L2 at 117V. What's causing this?

Hence the reason OP is seeing the voltage mismatch..
Given that the pedestals would presumably all be wired identically, it would be very odd for a campground not to wire up half the pedestals in the loop with the two legs swapped from the other half of the pedestals, such that the 30A sockets would tend to balance each other out. There's nothing other than an arbitrarily chosen convention that makes one particular leg L1 rather than L0, after all.
Sense that makes however......
Have observed a park re-wiring several sites. Even lent a hand (Steading the posts while the park paid employee, a friend, shoveled dirt around it and tamped it down)
They ran a bunch of BLACK wires.. Now they kept track of N and G but the two hots were both black. all black. no way to tell 1 from 2 at the box. So it is likely some 30's are L1 and others l2
But it's possible all one or the other.
And in another park (two others actually) have observed electricians working on them. again both L's were black. And Black is Black (I want my baby bac... Opps that's a song)
