We have a rear kitchen and our trailer also has shocks. I don't think we get any more jumbling than we did with our center kitchen without shocks. All travel trailers get the shakes and jumbles as far as I can tell. That is why you find all these nice little things for holding your items in place.
We all seem to want to travel way way faster on these wonderful roads than we should for items to stay in place. I myself need to plan for more road time. I know that 55 seems slow but it does not jar nearly as badly when going over bumpy places.
