Parkworld 885927 Shore Power Adapter Cord RV 30A 125V L5-30P Male to Marine Twist Lock SS1-50R 50A 125V Female (Yellow)

I replaced all my dock connection cords. This is over $100 less than west marine and same quality.

Replaced one of the $220 ones that was accidentally dropped in the lake. Works just as well.. so happy I bought 2 of them!
