Also, there is only one 'primary' 30amp breaker on your generator, but it controls BOTH 30amp sides of power - it's just a single handle instead of two, since, of course, it's also ONLY 120v power for each side. If one trips, the other does, too, but a flip of the primary breaker resets both at the same time.

Did you notice his generator is 7,000 Watt propane Koehler, not the more common Onan you may be familiar with? Or that the motorhome is a 1996 Damon Intruder on Freightliner chassis? That is a large unit.

I’m not sure how these older generators worked, but a family member had an older GMC with Honda generator that I believe could be wired for 240V. Also, my son recently purchased a portable generator (less than 7,000 Watts) for hurricane backup power and it’s 240V capabable. Just saying that without documentation, it’s difficult to know what he’s working with (unless you're familiar with Koehler generators).

The only reason I would question your assumption is that at 7,000 Watts, or 2 X 30 Amp circuits, if they are in same phase, it could exceed the current capacity of the neutral wire. My guess is that wiring is sized to the 50 Amp motorhome rating without much excess.
