Trailer Tongue Jack Confusion: Tip

It never fails!  In the heat of the moment when I'm just a couple of cranks away from getting the trailer off the hitch OR perfectly level... it happens.  I go the wrong way.  It's time to break out the 'Marks-A-Lot' and give yourself a break.  My guess is your handwriting will be nicer than mine.

It is cheap and easy and saves me a ton of time.  In my case the U and the D indicate what will happen to the WHEEL of the jack.
