Replacing a 30 amp male plug on Class C umbilical cord

I had that same problem with mine and they didn't make a small enough replacement plug head to go back into my TT. I had to duck tape it when I traveled. I finally found one last year, they just came out with this new style. I also got one from home depot but it was junk and would not go into the small storage hole either. like I said thereis one out there, just have to get an rv dealer find it for you.
