I also had this problem. I was lucky enough to have an electric dryer plug near the garage, and got a "splitvolt" brand switching box, which is awesome.
I literally dressed Karlach in a clown-like uniform and gave her all the clown parts so that I would know where all the clown parts are, and now that system doesn't work anymore. :(
My condolences, that sucks Glad you were able to find something that's worked out for you at least! If you ever need to tow random stuff but don't want to store a trailer, harbor freight makes one that folds in half and stores vertically.
that visualization doesn't help, at all
