30 amp RV outlet at home

I recently converted from a dual hot water tank setup in my house to a single tank resulting in an unused 30amp double pole breaker. I would like to use this breaker and the 10ga wire to power a TTL-30 outlet for my RV when it's in the driveway. Since the double pole is 240V through 2 conductors and I only need 120v is it acceptable to terminate the red conductor and just use the black (hot) white (neutral) and bare (ground) on the double pole breaker?

Thanks

    I would have exactly the same question, but when I think of how 240 doesn't use or need a common, its probably true.

    Also, if you are going to reuse existing wire, cap the unused leg to prevent it from touching something.

    Just swap out that breaker position with a single pole 30A breaker then cover extra space with a 'filler plate' so you don't have an open space in panel cover
    Or stick a 20A breaker in slot, don't connect any wires and left it off.

    Filler plates at Home Depot/Lowes---couple bucks

    That is my main concern that the breaker wouldn't trip on a 30 amp load on one leg of the double pole breaker.
