One of the on-going irritations of living in an RV has been the way the living room moved when the other person was in the bedroom. Anything other than shallow breathing felt like a Zumba class was being held in there. One evening I got mildly motion sick while Lori was making the bed.
So we got a Camco King Pin 5th Wheel Stabilizer.
It’s not like living in a stick built house, but the motion is way down. A great less-than-$100 addition to our home on the road.
