We have one and have use the cord several times. When we arrive at a campground with a great view but would be lost if we backed into a site, I pull in forward. Then the reach is too great for the hookups so we have long lengths of everything, power, water and sewer. This allows us to enjoy the view out of the front of the motorhome. Have never had a park complain about us being forward in a back-in site YET! Normally I have looked at the campground ahead of time on GoogleEarth so am well prepared before we arrive and have picked the site/sites I wish to camp in. Also have used the second cord to use my cheater box to build a 50 amp service out of two 30 amp service should the adjacent site is vacant and only 30 amp is available.
