Generator amps?

I picked up a Honda 7000, 48 available amps but split between a 30 amp outlet and a 20 amp outlet - separate circuit breakers. Is there any adaptor / power manager that would let me combine those 20 and 30 amp outlets so I can draw all the amps to my 50 amp plug?

Honda may have something but I'm sure no expert. They do to combine output from two of the 2000's.
It may not be possible but that depends on the internals of the generator.

BTW: if your RV is set for 50 amps you theoretically can draw 100 amps as each leg supplies 50 amps. Even if you could combine the output of the gen you'd have half of the real 50 amp circuit.
20 amps = 20 X 120 = 2,400 watts
30 amps = 30 X 120 = 3,600 watts
20 + 30 = 6,000 watts
50 amps = 2 X 50 X 120 = 12,000 watts

Make your own adapter. It's all wiring, no logic involved.

You can take a 50 amp pigtail and put a 30 amp plug on the black and white and a 20 amp plug on the red and white. The white neutral is common to both circuits. The green ground would also be common to both circuits. You may also have to combine the white and green at the generator. The RV expects the ground bonding to be done in the power pedestal.

You should be able to get a 50 amp range pigtail at any home improvement or hardware store. You will need to do the splicing in a 4" handy box with cover. Easiest way to make it would be to use 30 amp and 20 amp pigtail adapters and cut the receptacle end off. use cable restraints on the splicing box.

No that probably won't work. There's a Camco adaptor available but it doesn't work with gfci circuits, which my generator has. So I need a way to prevent an adaptor from tripping gfci. It's a floating neutral generator so I don't know if I'll cause grounding issues too.

If the GFCI keeps that from working, you will probably have to feed the 20 amp directly to a load, possibly the second AC or Microwave and put a transfer switch on that circuit.

That's a good idea. I was thinking of using the 20a to charge my batteries but the shore plug also charges batteries, so I don't know what the system will do with 2 inputs.
