I have a new 2017 (possibly a 2016 F53 Ford chassis) Thor 29.3. Read a lot about the CHF. So dragged myself under the coach and was surprised how easy the rear set up was to change. However, the front sway attachment arms are to short to move to the other position. It brings the sway arm up and hits the chassis. If someone had an idea on any longer arms and where to get them I would try and move the front arms to the closer holes. With just the rear having the mod, it still worked pretty well but not what I expected. I still get quite a bit of movement from semi's. I'm also going to try installing vortex generators on the rear and in front of the wheel wells. I will update when I get it all set up. It's getting pretty cold where I live and I want to paint them to match the color on the coach. So it may take a couple of weeks.
