I added rear sway bar, rear track bar, and safe t plus steering. All this helped with handling, but i feel there is too much correction going on continuously with steering.
When i was at newmar a couple of weeks ago, i ran this by a ford tech there, he suggested sumo springs. He said it will help that steering issue some. I did not think it would too much, i thought the springs were more for pitch and roll.
Any thoughts on this before i drop some $$ on this.
Any suggestions to improve the constant steering inputs.?
I have a 2020 Canyon Star 3710....and just an "FYI" or "Reference" here is what I did. And having returned from a 2200+ mile trip; I must say I am very happy & impressed with the ride & handling!
Prior to picking up my coach at Newmar, I had already purchased the items I was going to change.
1) Ultra-Trac rear trac bar
2) Set of 4 Koni shocks
3) Saf-T-Plus steering stabilizer
4) Front Sumo springs
5) Per the Ford Dealers recommendation; with these changes; did not do the "CHF"! Local Ford Dealer did all the installation work.
6) Newmar weighed the coach, & based on those weights, am running 95 PSI front & 88 PSI rear. Sorry, I don't have the 4 corner weights with me, but used the Michelin chart & I added 3 lbs PSI as a cushion.
My results; the coach rides quite comfortably, except harsh bridge transitions, or big potholes, which will rattle any coach.
Very little, if any movement from passing trucks, or the wind.
Expansion joints, & most bumps in roadway give slight feedback, but not much. In some cases, none whatsoever.
Almost no lean & roll, though some entrance approaches are such that it will lean a bit.
Drove 800 miles home from Napanee, towing a Terrain through the mountains of West Virginia & Virginia, and must say the coach did well! The tow/haul mode is a must to use in the mountains, but I use it almost exclusively.
Made a 2200+ trip down I-95 to Florida, across Florida to the west coast, back through the Ocala National Forest, to the east coast, then back up I-95 to Virginia.
I do not have to "battle" the steering input, I enjoy driving it, and after a day of driving, am not worn out , nor very tired. And at 73 years old, that's a blessing!
Afterthought: Get the coach weighed. Setting tire pressures with the Michelin guidelines may be a big help with the ride! Undoing the "CHF" may make a difference too. Ford Dealer mentioned it could cause more harshness in ride characteristics. I do not know, as I've not had that done to mine. And lastly, KONI shocks will make a big difference, they did for me.
Best of luck, hope this info may help, and be safe, & Happy RV'ing!
