Have carried a extra 25' with each of our three campers. Used it maybe a half dozen times. Each of them seemed to have a factory cord in the 20'-25' range. Most of the time has been when I have parked the wrong way in a site, so the pole is then on the wrong side. Those I could have just parked correctly if I had not had it. But I have been at a couple sites where 2 sites shared a pole, so ever other site it was on the wrong side for most trailers. There having the extra cord was my only choice.
