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 ...

Why not pull 120/240v service off the existing circuit?
At least double the power and much less effort.
Why not give him a can of gas and some matches?
The existing service is a 30A/120v circuit. 30A requires #10, but they used #8 when installed because of the distance.
If you are suggesting that he split that hot leg into 2 to create 30A/220v, he will overload that neutral and cause a fire.
A 50A RV plug uses a 240v feed from the panel but splits it into two 120v circuits at the RV. You need FOUR conductors: 2 hot legs at 120v each, a neutral and a ground.
Hence the 3-conductor alum wire the OP has will not in any case.
