The closest thing we have is the Mighty Cord RV Extension Cord - 30 Amps which is not a twist lock. The female end simply plugs straight into your RV 30 amp outlet and then the male end plugs into your power hookup. This comes in 10 foot length # A10-3010EH and 25 foot length # A10-3025EH. I attached a demonstration video for you to check out. view full answer...
