RV 30amp Outdoor Circuit

I have an existing outdoor disconnect for a previous Hot Tub I had with what appears to be #6 wiring for a 30amp dual pole gfi breaker. Looking to install a 30amp circuit for my RV and ran 10/2 wiring in conduit about 70ft out to a post in the yard. I'm replacing the dual pole 30amp breaker with a single. Question: Can I use the existing #6 thick wire to the disconnect box and connect the 10/2 from there.. or do I need to run the 10/2 back to the breaker box? Getting the existing wires out and running the 10/2 into the house is going to be a pain.

The larger wires can stay.

What kind of cable was the 10-2?

That is only okay if the disconnect is mounted on the house and the NM-b comes in to the back.

If cable it must be UF but best practice would be to use individual conductors such as THWN. Cable is harder to pull.

Type NM-B cable is for indoor dry locations only and cannot be used outside the house. All outdoor conduit is considered wet locations whether above or below grade.

That will need to be replaced preferably with Type THHN/THWN individual conductors.

For now you can keep the #6 wiring to a junction box and extend the #10 UF (cable) or THWN (individual wires) underground from there. Use a 30 amp breaker at the panel for the #6 line.

At a later date you can put a subpanel where the #6 ends outside, add more breakered circuits from there, and up the rating of the panel breaker for the #6 line.
