Toting RV power cord

I use a cord reel. You can get them at Lowes. Just place one end into the reel, and reel / crank the cord in. Takes very little space, 4" wide, and 13" or so, across and prevents ALL tangles. The reel is around 9 bucks, and is orange. I have 2 cords. One reel for each. I also use the bigger reel for my fresh water hose. Same thing. Place one end into the reel, and wind it in. It empties as it is rolled up.
And they never unwind in the storage bin
