Not exactly, when you use a 50 amp female to 30 amp male adapter, what the adapter does is jumps the only ONE 30 amp 120 volt leg over to both the L1 and L2 sides...so that way both legs are powered in the 50 amp RV....but they are sharing the same 30 amps L1.
This schematic may help as you can see the jumper/adapter on the far right to understand how it works. I do not like the way it says "split" as it's actually "shared" between the L1 and L2...but you can get the gist.
The OP is adapting from 50 amps to 15 amps on his generator, but it still all works the same. He is going to be sharing the L1 15 amps across both his L1 and L2 in his RV. Everything is powered.....but just at 15 amps (1800 watts) total
