Perhaps there has been some mis-understanding... I never planned on using the stabilizers to support the camper! I was asking if I could raise the trailer with them, and then place jack stands under it.
what I ended up doing was cranking the front jacks way up and placing jackstands under the frame forward of the wheels, then using my floor jack raised the rear of the trailer up and place another set of stands under the frame rear of the wheels. Then I lowered the front jacks till they were just touching the ground and lowered the rear stabilizers so they were just touching the ground giving me 8 points of contact with the trailer raised off the ground.
Axle flip is completed, brakes are serviced, wheel bearings re-packed, and new tires going on today... then out for the maiden voyage this weekend, we're going to try and get some fall camping in before freeze up.
