30 amp / 50 amp
We're considering a new FW and a couple of the options are upgrading the single AC to 15k with 2nd AC prep (I believe the prep is standard). There is also a 30 to 50 amp option. First question; if I...

Since very few RVs have 240V appliances the simple explanation is that you have 2 50A circuits for the RV which is a lot of power. Some loads on one circuit and the rest on the other circuit. And yes they are protected by a dual ganged 50A CB for safety. If you overload one 50A circuit both will trip disabling all power in the rig.
So why is it called 50A when it has 2 50A 120V capability or 100A total? The circuit description is 120/240V, 50A, 4 wire, 3 pole, 60Z. The 50A designation refers to the higher voltage (240V) and indeed 50A is the maximum a 240V appliance could draw. The plug is also a standard household plug and circuit. And some homes use this plug for their 50A ovens which use both 240V (heating element) and 120V (light, etc).
What I said, but not as elegant! The point is with a "50 amp" you have a lot more power for things in an RV, even 30 amp wired RV's should plug into 50 amp outlets with adaptors, at peak times when using AC, TV, micro wave, and hair dryer that will give them some "fudge" factor.
Not a good idea. You have a 30A cord plugged into a 50A breaker.
