Yep you read that right,, wiggle..we just got into our new big fifth wheel and find that it wiggles alot more than our little one did.. It has the 6 pt leveling system, but the back has the slide outs...
We are full timers and have the 6 point system. I have had great success by placing 2x10x12" treated boards under each stabilizer regardless of the surface we are setting up on. We have been doing this for 4 years and although it does not eliminate ALL movement it is very effective. Only adds about 1 minute to set up time and have only had to replace them 1 time in the 4 years. Home Depot will cut them to any length for you for only the cost of the board.
