220 double pole breaker to 2- 110 /one rv 30amp

I am in the US. I have a 30 amp 220 double pole breaker already run to a box on the outside of my house. I would like to use the box outside and run service 100 ft away to a make an rv outlet for 30 amp 110 service with a separate 110 outlet in same location. From what I see the outside box only has 2 hot and one ground. Can I run this line 100 ft away and then split it into 2 110v lines with one being for 30amp rv service? Do I have to run two separate lines from the interior panel and two new separate 30 amp breakers?

Note: standard voltages are 120 or 240 in homes.

The short answer is no. You can't have two separate 120-volt circuits to your RV hookup as you only have 3 wires in the current setup.

However, you can have a 30 amp receptacle and a 20 amp receptacle at your RV hookup using a box like this: https://www.menards.com/main/electri...4429562571.htm It is just that they would be on the same 30 amp circuit. You will need to adjust the wiring to one hot and one neutral and install a single-pole breaker.
