Who Manufactured our 30 amp Electric Cord?

Good morning everyone! Does anyone know who manufactures the 30 amp electrical cords for Forest River Rockwood Roos? (It is black on the plug end and has a yellow and black screw-on end at the camper end, but I don't see a brand stamped on it.) Ours has gone bad, and will just stop working for no explainable reason, and when DH goes outside and wiggles it, the power will flicker on and off until it gets "just right" and will work until it just randomly quits again. Frustrating. Especially when it's pouring down rain. :) Anyhoo, FR has told me that it's not covered under our second year warranty, but I figured it couldn't hurt a thing to contact the manufacturer directly and see if they would help us out, seeing as how it's almost $100 to order a new one.

I guess a followup question to that will be, if we do end up having to buy one, is there a particular one that might last better than the original one did? We have not stepped on it or pulled it or anything, and I suspect the problem might be because of the way it sticks out awkwardly from the camper rather than going downward, if that makes any sense at all. Haven't finished my coffee yet this morning. :) Thanks, everyone!
