20 &30 amp to 50 amp adapter wiring?
I want to make my own and adapter box to come out from a 30 amp and a 20 amp outlet in the power pedestal to a 50 amp outlet. (See a couple of examples of what I'm referring to below). Does anyone...

My experience is it would be better to have a 30/30 cheater box instead of a 20/30 as any new or remodeled pedestal is required to have a GFCI 20amp receptacle. The cheater box will NOT work on a GFCI protected circuit. Save your money and effort......Dennis
But...if you decide you still want to go for it, here's what you'll need.
About 2' of 10/3 wire
About 2' of 12/3 wire
One 125VAC 30amp trailer plug
One 125VAC 15amp 3 wire angle plug
One125/ 250VAC 50amp 4 wire surface mount range plug. Make sure you waterproof it.
One 1" waterproof connector
Take both green wires from the plugs and wire them to the ground lug of the 50amp receptacle.
Take both white wires from the plugs and wire them to the neutral lug of the 50 amp receptacle.
Connect one of the black wires to the L1 lug of the 50 amp receptacle.
Connect the other black or red wire to the L2 lug of the 50 amp receptacle.
Make sure you waterproof the 50 amp receptacle.
NOW FOR THE CAVEAT....
BEFORE you plug in your COACH, TEST IT!!
Using a meter, connect L1 with the common. Voltage should be between 110VAC and 120VAC.
Connect L2 with the common. Voltage should be similar as above.
Finally measure between common and ground. Voltage should read 0.
You should get the same readings, measuring both L1 and L2 lugs with the ground lug.
Remember, I do not recommend using one of these devices as different campgrounds are not all wired the same. Lots of weird combinations out there with a lot of redneck wiring jobs. I take zero responsibility if you fry your coach using one of them......just sayin.....Dennis
