If you were to build a box with 3 amp meters mounted and run line 1 to one and line 2 to the second one and the neutral to the third one.
When you turned the first 20 amp load on line 1 the amp meter for line 1 and the amp meter for the natural will read 20 amps.
Then when you turn the second 20 amp load on line 2 you will read 20 amps on line 1 and 20 amps on line 2 and 0 amps on the natural.
The neutral only carries load when the loads are unbalanced.

That is true, but to most, it is way over their heads. It is better to just say, you are getting two separate 120 volt legs, each with 50 amps of capacity on a 50 amp wired trailer. If you happen to be in a park that is wired 208Y/120 volts, and they are out there, then that adds to the confusion, because there isn't 240 volts. When you have separate loads on the opposing hotlegs in one of these panels, you really do not have a 240 volt connected load. A true 240 volt load does not utilize the neutral like the 120 volt circuits do.
