If you are looking to have your coach aligned or handling improvements made in northern Illinois, check out Champion Frame Align in Elgin Il. Checking for Flash...
I have no affiliation with them. I had my 2014 3170 Sunseeker aligned there. I thought they did a good job.
They stock the bushings needed for the e series Ford chasis. They handle class A coaches as well.
They made a number of suggestions for improving the handling (sway bars, track bars, shocks, steering centering device). They gave me a written quote for all those items with parts and labor broken out. They explained what each part would do but they were not pushy.
Overall a good experience. Figured I would share, as finding a place to have a coach aligned can be challenging.
