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?

Such imbalances can also be caused by poor neutral connections; when the neutral has a higher resistance than it should, its voltage tends to float based on the relative loads on the two legs. (The extreme version of this is an open neutral, which generally causes lots of problems and lots of expense in a short period of time.)
If you're seeing such voltage variations pretty consistently, it would be advisable to verify that your RV's power inlet connections, transfer switch connections, etc. are in good shape and properly tightened down.
