Thanks all, this is super helpful. We just bought used 2016 ACE 29.4 and the previous owners installed the SuperSteer in the rear but did not do the CHF so I'll be looking into that. Silly question I have, what do you mean "weighted"? Do you go to the weight stations on the highways? I know in CA, we wanted to do that for our travel trailer but there were signs that it's not allowed. So trying understand that.
Also, do you get alignment done before CHF or after? Just wanted to be sure there wasn't a specific order I should follow. We also found a bushing falling apart on driver's side which I believe is power steering bushing? Right now, we seem to have some slop that we are always over-correcting the steering wheel when driving and it's also crooked. I'm not sure we have much issues with winds but seems just driving the coach, it requires lots of effort to keep it straight on the road.
