I posted no "misinformation". Mine does tuck up pretty nicely. Ground clearance with a SL depends on how much low hanging stuff is under your truck and how low your truck sits.
And when you do whack a camper jack leg, it rips out. When you whack a Stable Lift, usually nothing happens.
How many times have you heard of a camper jack being torn out? How many times have you heard of a Stable Lift being damaged?
Holy cow, look at how far extended those Stable Lift frame brackets you showed are! Mine aren't out nearly that low! You've posted an extremely low SL and an unusually high-clearance pop-up camper. I call that stacking the deck.
