That is correct. 51 amps minus 44 amps should be around 7-8 amps....they try to cancel each other since the current flow is in opposite directions.....and the larger current flow of 51 is partially cancelled, but 7 or 8 amps gets through. In your example it is 7.8....so close enough!

I loved the 50 amp. I can set at the beach under the blazing sun and run 3 a/c's if needed, elect. water heater, washer/dryer and microwave with no problem.

Small correction, you can get 240V using breakers on the L1 and L2 side, BUT you can't legally since you can't tie the breakers together (and it's very dangerous).
You can, however, put a subpanel in the trailer prior to the main panel to do 240v, legally, but there really isn't the need for the 240v in the RV appliance world.Curtis, Christine, Cole, and Charlotte

Although my trailer is 50A, I only have a single AC unit and will not need the full 50A. So, I purchased one of these adaptors for $20 and just use all of the 30A items from my old trailer. I use the 30A extension cord and 30A surge protector. No need to use the huge and bulky 50A cable or surge protector. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

You are correct, BUT, the purpose of my post was twofold. 1. To explain what the actual system is and how it works. 2. Stay within the bounds of Electrical codes that provide safe usage of the system. I'm sure there are many ways to "bastardize" any system....but we are trying to keep it within the electrical safety/functionality, and code guidelines. So basically, no correction needed on what I wrote.

Actually, I wasn't pointing out how to bastardize anything. I was saying the voltage was there. So I guess that would be a small correction.

Good discussion, just wanted to add this here. 30A is not enough at all. I leave the water heater on, 1 AC running and Ninja foodie or microwave at the same time pops the fuse/ breaker.
And 50A might be overkill but we could get to a point where it is necessary for someone with 3 AC and other things and at the time, instead of having a 3rd type of outlet and campsites, this might be a way of future proofing and it will be backward compatible.

Another option for the 30 Ampers.
In my previous trailer, I added a second 30A service with breaker panel. I had a PI EMS and did not want to buy another one, so I split my loads leaving the inductive loads on the EMS circuit for protection and the rest on the new panel. I also added a dedicated 20A circuit to run the space heaters. The total was 80A of service. Not 100A but good enough for what I needed to run. It didn't break the bank either. I think I had a couple of hundred $$$ in it.2010 Jayco 26(SOLD)
