Motorhome sway
My 40 Foot Class A after a long sweeping right turn and an immediate left turn at 20 mph almost rolled over. I've made many left turns at a greater speed without that reaction.

I read all 4 pages so far, and I have yet to see where the OP states how sharp the turns are or what the DOT's posted speed for the s-curve is. All that was stated was, "a long sweeping right turn and an immediate left turn at 20 mph almost rolled over"; yet about ½-dozen replys say he was going too fast, or driving it like it was a Porschorgini or something. If the posted safe speed is 25, and other coaches are negotiating the s-curve at 30 MPH without issues, is he still driving too fast at 20 MPH? The OP is obviously trying to fix a dangerous handeling problem and make it safe to drive.
