From the look of your picture. Your electrical work appears to be in violation of the electrical codes.
Are the 2 receptacles and the RV receptacle all on the 30 amp breaker together?
If so, you may overload that breaker if you have something plugged into the receptacles while running the loads in the RV. If you used 10/2 wire which is rated for 30 amps and have the full load of the RV and something else plugged into the receptacles with a load that combined exceeds the 30 amps it will cause the breaker to trip.
Another thing is those receptacles are not rated for the 30 amps supplied to them. They are 15 amp rated receptacles meaning nothing over that 15 amp rating should be plugged in to them. You run the risk of having a serious problem with something drawing too many amps and not tripping the breaker and catching fire since the breaker is too large for those receptacles.
Your 30 amp circuit for the RV should be a dedicated circuit and the receptacles should be on a seperate circuit that is a GFIC protected circuit since they are outside. The two different wires can not be run in the same conduit either. Easiest solution is to remove the receptacles and wire nut & tape them inside the top box and get a water tight box cover to seal them from the weather. Then run a new circuit protected with either a GFIC Receptacle or GFIC Breaker in the panel to outside near the same location.
I'm bringing this to your attention because heaven forbid if it caused a fire and was investigated your insurance company most likely would not cover your loss.
