Late to this thread. Out voting.
Some things to keep in mind:
1) Electricians need to understand that this is an RV plug and not a dryer plug. More than one thread here about some electrician friend wiring the 30 amp RV plug to be 220. Bad mess; it will fry all electronics in your camper.
2) While you can run 10 gauge 2 wire w/G for a 30 amp RV circuit, it won't work for 50 amp.
Shop Cerro Wire 10 AWG 50' Indoor Non-Metallic Wire at Lowes.com
50 feet of 2 conductor 10 gauge with ground $62.50
Additionally you will need 3 conductor w/G for the 50 amps service and two adjacent 50 amp breakers in the breaker panel.
Shop Cerro Wire 8 AWG 50' Indoor Non-Metallic Wire at Lowes.com
50 feet of 8 gauge 3 conductor w/G required for a 50 amp service $120.00
