I just got home.  It was 1300 miles and the coach was smooth and did not move on the road. No real correction required the whole way... I saw that someone else must have worked on the front end as Wayne said my shims were in backwards.

That is interesting John, Wayne told me the exact same words, so I wonder where they found the confused front end mechanic, or is it just a different setting for caster ?
Glad you must have found the same feeling driving the coach as I found on mine.
Good when it works so well.

For those not familiar with front end geometry, reversing the caster shims basically takes positive caster to NEGATIVE.  A very bad thing for tracking!

Brett, Maybe you were not paying attention to the fact that my and some others were set to the negative side, so reversing the shims, would take it to the POSITIVE position, which is the desired position for stability.  Were talking CASTER here.

I wonder if, possibly, the reversal of the shims was right to left?  I just looked at the tag on my coach and it specs left caster 51/2, right 41/2.  That's the factory tag, and if I'm not mistaken the right is supposed to have more caster than the left?

Left to right caster is how you adjust for running straight down the road without it trying to jump in the ditch or cross over to the other lane, also accounts for the road crown.
More to front end geometry than guessing.

I realize that.  So what is the recommended setting for caster in a non ifs Foretravel?  More on left or more on right?  There's got to be a standard setting.

I would quiz Wayne at FOT, he knows what, why and seems to have a good rep for doing wonders to ill handling Foretravels,  as to what the caster, camber and toe in setting he uses.
The funny part, I thought my front end was very good, this has to be due to alot of really poor equipment I have gotten used to, after Wayne did my coach, it was very amazing the improvement. Meaning alot less wheel turning to keep where I want it.
CHeck with him.
