Yep, I think you justified it quite well. :B
Now, doing a bit more thinking on this subject (overthinking?) I feel it would really be a good thing if you did purchase and use that controller - that is what I would do anyway.
I, as of the end of this winters trip to Texas and back to Michigan, have quit traveling via RV and will use our trailer for a "summer place" in my son's beautiful family campground in the woods in northern Michigan. I have one more tow to do and that is take our trailer from the lower part of Michigan up to his campground, then that is it for us.
If I were going to continue towing, I would purchase one of those controllers and give it a try. Craigslist is my friend in case it didn't workout well! :B
Did I do ok on my over-thinkingness ? :W
