I drove it first and went with Safety first, I bought the Safe T Plus Stabilizer bar. It kept the RV to go straight on the road. I had my 1st blowout 2 months ago, on a Interstate at 70 mph and the RV kept straight. If it wasn't for the bumpy noises I couldn't tell. When I pulled over to check, I went to the back of RV to check tires; thinking everything was ok only to see the right front tire was gone while walking back up to the coach.
The Safe T Plus has helped when getting pushed by trucks because it is easy to hold steady to recover. Before it was a little back and forth trying to recover from being pushed that was kind of scary.
Safe T Plus is A+ in my book.
I later would add the Sumo Springs. I saw immediate impact when turning into parking lots, and making left and right turns. The ride slightly improved, but still bumpy as hell. But the rock and sway is dramatically diminished. I don't feel trucks any more, but I drive better and with more confidence now. It is rare a Truck is passing me
I think Sumo Springs are way over price, especially now. I am glad I have them, but I feel like I got ripped off in broad daylight. I struggle to decide whether to give them a value rating of C+ or B-? I think if they were cheaper I would say B-
I did not do the CHF and I have no plans to do that.
In hindsight, before I bought the Sumo Springs, I was at a Spring Shop in Dallas and the guy laugh when I told him of my plan for Sumo Springs. He said the only way to get a smooth ride was to replace the leafs and redo the springs? Well I am not the Duckface guy and didn't know what all that meant, it sounded like too much for me to do for a brand new coach, but I wonder if I should have listened to him, or at least did more research?
FWIW, I was at a Spring Shop, because they mounted my bracket for my Safe T Plus when Ford's Rush Truck Center couldn't get the U Bolts off
Update:
FWIW #2, I upgraded my hitch. See this link for picture
https://www.thorforums.com/forums/sh...0&postcount=62 or scan the thread to see why I went with a 10,000 lbs rated hitch. It was installed on the Ford Chassis main frame, the OEM was mounted on the WBO extension frame.
