Wire for 50A 220V Service - 110' run
I have on hand about 30' of #2 aluminum wire and about 100' of #6 aluminum wire. The run from the breaker to the outlet will be about 120'. Can I run about 30' or so of #2, then continue with #6 to ...

I hope you are not thinking that you need 220v for an rv. They use 120 v , 50a.
Please refrain from offering electrical advice.
Well--yes and no. 50 amp rv service is two lines of 120V each, 180 degrees out of phase with each other. 220V across them, however the rv's use each line of 120V separately for about half the things inside the rv.
Only things that might use 220V would be a clothes dryer, water heater, or electric furnace. My experience.
well i guess my house is 400 amp 120v?????
this is stupid if the circuit can provide 220-240. its a 220-240 circuit. rv 50amp is 50a/240v. no matter how you look at. regardless of what is used in reality on the circuit
^ this is the correct answer.
By NEC definition, RV 50 amp is a 120/240 60 hz 50 ampere supply. It doesn't matter what is used or wired within the RV, the supply is what it is.
I wish there was a competency test for posting answers to questions of certain subject matter.
The answer you quoted as "correct" and your NEC definition above don't even match. A 240V circuit is 240V but a "240V" circuit doesn't need a neutral. When you include the neutral, it is now a 120/240V supply.
Overactive boldification.
