Our Magna is one of those "odd" ones in that the dryer is a 240 volt unit. Nothing else is though.
And a 50 amp RV will have 50 amps available on both legs. 30 amps is 3,600 watts and a 50 amp RV will take 12,000 watts
120 X 30 = 3,600 watts
120 X 50 X 2 = 12,000 watts.

Ps. As to the box having two 50A legs, this box has the capability to use 220 volt 50 amp max or 30 amp, which ever is available. Having only 1 a/c unit and microwave, can run to capacity on 30 amp. Initially, I purchased a 3500 watt 110 volt gen set but in the upper elevations, the engine wasn't powerful enough to get the full output. Couldn't start or run the ac and microwave at the same time. Upgraded to a 7500 watt unit so now it has the 30 amps on two legs but only requires about 15 to 20 per leg for max appliance usage. I suppose on some of the larger coaches, maybe they have the capability and need for a 100 amp service???
