We have a 15 year old alpenlite with the old fashion landing gear and rear stabilizers. A couple of years rving my wife wanted to end the wiggle for doing her needle work as she sits over the tires. I installed scissor jacks in front of the tires. Still using this method for our 6 months each winter but did install the JT Strong arm product. They are an awesome product for ending the wiggle and when the wind blows. I do hear from the newer fifths owners with the auto systems complain of the wiggle they were excepting to not have and not as level as they thought the result would be. Sometimes I can see they are not level. I do know when we park at home on concrete and not setup the strong arms the fifth is really solid and feel the problem for the guys not liking any wiggle the ground is the main reason. I have been in large MH's that wiggle.
