It is correct that you can’t lift with three jacks, 1 front and 2 rear. You can though lift with 2 front and 1 rear. Like someone said it used to be 3 jacks tho they were not even front to back, one was about middle on one side. Huh? So while on the supports, remove the bad front and replace with a good rear. Walla, good to go until to you fix the now rear jack. A big yes to putting the bad jack on the back just in case it does tip, a little leg is better than none. And yes, probably a shear pin on the gear or the mechanism with the lever that transfers from manuel to auto, it’s plastic. I rebuilt mine last year but sitting here now the memory is a little foggy. Also, let a lot of air out of your rear tires so you don’t have to lift the camper as high. Maybe down to 15-20 lbs.
