I've thought about doing this MOD but where we usually camp, I never have to pull the cord out of the "rat hole" more than 10' or so and never have an issue stuffing it back in. I thought I read somewhere on the Forum that it's best to have the entire cord pulled out no matter how long it was to the hookup, but I've never had a problem electrically with this method.
