30 amp adapter

Somehow I ended up with what I thought was a 30 amp extension cord for my TT. Pulled it out last night and found it has a 30 amp RV male on one end and a 3 blade twist lock marine female on the other end. I checked CW and Wally but don't see an adapter to go from a twistlock male to a 30 amp rv female. Did a search here and got zero results. Would I be better off getting rid of this and just buying a 30 amp rv ext? Maybe I should just cut off the twist lock female and put on a 30 amp rv female.

  • Make sure all of our connections are really tight if you make your own. Had a loose dealer made one cause all kinds of damage. A factory made one with molded ends for me. Might get a fair price for yours on Craig's list. Help defray cost of new one.
  • when you cut that marine twist female connector off, leave about one ft of wire on it. then put a 15/20 amp male plug on it and you can easily run a standard extension cord to it when stored at your house to keep batteries charged, etc.

    Your extension appears to be a 30AMP Cord that connects to a standard 30A RV Trailer twist-lock connector. You may only be familiar with the pull-out Cords alot of RV trailers have.




    The RV 30AMP Extension cord will look like this.

  • Thanks guys. I should have thought of that one before posting. CW Tampa has it in stock, Ft Meyers- definite maybe. I'll find one. Seems a shame to cut an expensive cord, but it won't work for me as is.
  • You can also make your 30 amp extension cords way cheaper than buying one.
