This product review is based on the first hour of ownership of this RV cord, so the long term usage hasn't been taken into account.. Our travel trailer is just over 14 months old and 2 months out of warranty. The other day I noticed the power was off in some of the garage's outlets as the GFI had tripped. The trailer parked outside the garage was also without power as its plugged into the same circuit. I reset the GFI and it tripped again. Troubleshooting the problem I found the trailer's supplied power cord failed for no apparent reason. Luckily it happened at home while plugged in and not when we were away camping hundreds of miles from any RV dealer. Once I figured out that it was the cord by using a multi meter [short in the wires] and not something else, I checked the prices on 鶹 and found this cord and quickly ordered it. It arrived the next day and I plugged it in. It fit better than the old one and seams built robust enough to last as it should. The carrying handle and adaptor plug included are an added bonus.
