OK, I have a camco RV plug on the end of my cord.

even though I like the function of it, the damn thing falls apart every couple month's. and I have a short, and I have to pull it apart and reconnect the wires inside. the stress reliever on the end just does not hold super tight.

I am not interested in downsizing, because I run both roof airs all the time, and I have a nice 50 amp outlet by the garage I plug into.

I am thinking of filling that camco thing with some epoxy. any other thoughts of how to have a more "factory solid" end to the cord?
or what epoxy I should use that will not eat the plastic, or corrode the copper, or be conductive at all?

the one's on my extra extension cord you can tell are molded, not assembled, and will not come loose.

I have thought using leveton, or other more brand name electrical plug, but I do like the handle on the camco.
