I have a Blue ox coiled electrical cable that runs from M/H to Toad. I purchased it in 2010 from Blue ox. I have noticed that the outer covering of the cable has many cracks from one end to the other....
My Blue Ox cable has been plugged into Motor Home over 8 yrs and have had no problem. Hitch stays in but I always put the cover on it. I just wrap the cable around the hitch and make sure plug is pointed down. Taking hitch and cable off would be the best tho but we usually dont go more than 6 wks without using MH and I keep it at home.
