We had a 99 31' Minnie Winnie that had a bad handling problem with rolling side to side. We added heavy duty roll bars with urethane bushing to the front and real and Bilstein shocks to the front and rear. Drove 200% better. Went from fighting to keep a straight line to one hand driving.
A steering stabilizer will just mask the problem and not cure it.
