Scratching my head here, going "I know I responded to this". Now I realize that this same request is posted both here and on the "other' RV forum.... Which is OK, I don't have any problems with that......... So I will repost here what I posted over there...........

By the way, mine is the 12,300 lb GVWR. It handles quite well at highway speeds, but I am getting a lot of side to side movement at low speed on uneven pavement. Think pulling out of a gas station-cupboards have opened and dishes have gone flying!
Thanks
Continuing back and forth sway after passing over a curb cut like you describe is not for lack of a anti-sway bar, but rather shocks. Heavy duty shocks will dampen this side to side movement. In fact, adding a heavy anti-sway bar will actually increase the uneven surface type of side to side movement. This is why rock crawlers and off road jeeps and such either do not have anti-sway bars or have ones with quick disconnectable end links. Going at an angle across a curb cut requires the suspension operate independently and if it does not (and the AS bar prevents this indy movement) then the entire vehicle follows and you get the rocking. The shocks are there to dampen this and prevent repeated oscillations.
You probably do need the anti-sway bar however, to help with the "being blown off the road by a semi" effect you probably experience.
If your MH has any miles at all on it, I can assure you, the rear shocks are totally worn out. They probably were not heavy duty enough to start with, and the extreme weight only worn them out faster.
My Sprinter chassis View had a larger Roadmaster AS bar installed when I got it. I still got the blast from Semis, (the View is tall and narrow so this is more of an issue than a Ford or GM chassis.) I finally installed new Koni Red rear shocks set full stiff, and also replaced the rear 3T add on air bags (which would no longer hold air). End result was an end to the white knuckle driving. I later added front struts, Koni Reds, also full stiff, but the original struts were quite stiff and so the Koni's made little difference on the front.
