We put scissors on our Axis:
Front:
Rear:
We've only used them on one trip so far (put them on last fall) and they didn't completely remove the rocking from our E-350 framed unit. Each jack, however, is good for at least 5000lbs so I should be able to really crank them down and take most of the weight off the wheels.
I'll know more when next season gets underway...
When parked on our driveway our unit cannot run the fridge due to the angle--I have to lift the front a good 6" for the fridge to work properly.
