This can happen on a 30 feed. You are sharing power with the pedestal in the next spot.
When this happened to me I was plugged into the 30A plug.
The Motorhome next to me had only 80 volts and I had 160 coming into my rig. The one with the higher load will have the lower voltage.
The voltage will depend on the load on that phase.
The only way you can get a 160 vac to neutral is when you tap into an industrial 3 phase 440v 120/208 source that is common in industrial plant.Even with 160 v would indicate a faulty transformer from the utility company. Power supply for residential or any occupancy designed for human habitation which include RV (in North America) are normally supplied with 120/240vac. We are talking about losing the neutral which is not indicated in the problem you experienced. The standard 30A rv plugs only carry one hot and one neutral-so where did you get the other hot leg?
I am a retired electrical engineer and used to design power distribution systems for a living for almost three decades.
