I have a 3013 class c 23 foot thor mh and I up graded the rear shocks to Monroe coil overs and the front to heavy duty Monroe rv shocks and then put on the Monroe steering dampner. this made a huge difference.
But then I was still not satisfied with handling so I upgraded the steering dampner to a bilistine and added the hellwig sway bar and OMG what a difference it handles like a mini van now I can take my hands off the wheel and drive with finger tips now with out surprises.
If you are thinking about doing this modification just do it it cost me like 325.00 (DAMPNER AND SWAYBAR)I would pay 2 times that it is easy to install if you can change a tire you can do this.
the fractory sway bar is a joke compared to hellwig
the Monroe steering dampner is a joke compared to bilistine
the rear coil over monroes are excilent shocks.
YOU WILL NOT REGRET THE UPGRADES...........
THESE CLASS C SHOULD COME STANDARD WITH BILISTINE AND HELLWIG!!!!!!!
