I ran it connected directly to the camper power cord (25' 10g) and it still bogged down. I checked voltage drop on the long run and had 123.x volts on a wall plug in the camper. I used 10, 12, and 14 gauge wires to get to that distance.
A reminder...
Voltage drop is a function of load. As the load on the circuit increases and decreases, so does the voltage drop.
So measuring the voltage of a 400' loop of copper isn't really going to tell you anything if there is no load on it, since 0 load = 0 voltage drop. (Or, not much anyway, there will be a touch due to the wire itself, but at 120v it won't be much and might not even be noticeable.)
To find out what's really going on, one has to measure the voltage of the loop while it's under full load in order to induce the maximum voltage drop.
