Replacing 50A Electric Cord

I replaced the 30 amp cord. No big deal, just follow the end of the cord as it goes into the RV and find where it is spliced into the RV electrical. Remove the old cord and splice in a new one. The cords are generic. I had to remove a tail light to get enough room to work in. Just make sure to match the colors.

Is your cord detachable at the rig?
Fairly easy job in most cases. Some times you can get a 35 foot extension cord, remove the coach end for less dollars then buying parts.
It is hard to find good cable that is flexible. Most cable is 6/4 cable. Many RVs use 6/3 plus # 8 ground to reduce size and weight.
