Found a little info on line which states:
What causes voltage drop in wiring?
"Resistance between the voltage source and the load causes a voltage drop in wiring. A poor connection, corrosion, the type of wire being used, the diameter or gauge of the wire, and the distance between the source and the load can all cause resistance in wiring."
When I replaced the coroplast on the trailer belly I had a chance to check the wiring on the inside. I was a mess. Wires are not secured anywhere except at their connections. I found a number of wires that were rubbed quite badly and some that had already shorted out. And, ouch, I got a 12v jolt while running my hand along some of them where the wire was exposed. I replaced the damaged ones and secured them in split tubing.
That said, I think you may have a problem either at the connections in the outlet or somewhere along the line run. If its the outlet that should be an easy fix. If its under the floor, you will have a bit of work on your hands.
An electrician may be the route to go if it's not your junction box. They have ways of checking for broken wires that may identify where the problem is.
