I have two mounted at the rear of my 16' Casita but in a month and a half of using it, I have yet to try and figure how to lower them. I have never even felt the need to try and do so. Whether hooked to my Jeep or not, the Casita is always steady enough for me. Why is it so important to some? I cannot imagine there being the danger of it flipping backwards, which, I suppose, is the reason they are there.
I have Twice actualy tiped my 13' Scamp
Backwords... And My Wife and I are not large people... Our Scamp
is noisy and squeekey when its on just the wheels. I like it Firm.. Also they help alot with leveling out the trailer if I am on loose dirt or gravle...
BTW I use the Atwood Stock Stablizers on my older Scamp
.. They are worthless!
