We pulled in to our site last week and I started putting down the jacks. Front and road side jacks went down, curb side jack just went click, click, click. After a quick text to Steve (Scubarx) I lifted the bed and forced the jack down back on the track with the manual handle. I always try to stop before I hit the top when retracting the jacks, but not being able to see them requires a second set of eyes or constantly stopping and looking. Lesson learned, you might hear that click, click, click when trying to put the jack down if you heard the click, click, click when you raised it! Thanks to Steve for quick advice to help out a new owner.
