This is actually a good way to add extra breakers when you have no more slots to install breakers.
My house is set up kind of weird. The main power comes into the main breaker panel, which is outside the house and splits (after the meter) to the house and garage. One line inside the house is also sub split between 2 panels.
The other main line goes to the garage.
From this main panel, we had another line run for a 20-30-50 amp RV box which has served us very, very well.
Well, a few weeks ago we had installed an electric gate across the drive way. I needed an electric line run to the motor for the gate, and hooking into the electric system was solved this way.
The electrician used the breaker box for the RV. He took out the 20 amp single throw breaker and installed a double throw 20 amp breaker. One side goes directly to the outlet in the box, the second throw is attached to the new wire running to the electric gate motor across the drive way.
The entire RV outlet box is actually wired into an 80 amp breaker at the main junction and the electrician who installed that one used a 4 gauge wire (very heavy). (Thank goodness it was only about 3 feet long).
So, actually, what taylorbob1 suggested is a very do-able suggestion and probably your absolute best solution. Of course, you'll still have to dismantle a wall somewhere to install the new wire for the RV outlet. BUT .... everything worth while doing always comes with a price!
