My Voltage came with a storage reel located in the wet-bay side basement, made by MorRyde. ( Easy Reel - Tall - MORryde Products
I'm not sure if that was part of the EPIC package, or if they've just stopped including them with newer models. That said, I did make a couple of 'improvements' to make things even easier.
First thing I did was to obtain a slider-tray (MorRyde also makes those) that I could mount it on to make access easier. Slide it out to deploy & wind it back up... slide it back in for storage.
Next thing I did was to invest in a shorter 50-amp cord. I've only needed all 50' of the thing once or twice in 5 years... and most times, really didn't need more than 20'-25'. It got old having to unreel the entire length every place I went... so I not only bought a shorter cord, but also found one with a 90-degree plug AND a locking ring. Wasn't easy finding one like that, and for awhile the only one I could find cost over $500. Then a little over a year ago, Amazon began selling it for around $300, and I got it. Here's a link if you're interested:
I did keep my 50' cord too, just in case I ever need the extra length. I have it stored in the bed of my truck, nicely coiled & tucked in the previously unusable space beneath my cross-bed tool box.
