My Coachmen Mirada is about 14 years older than yours, so there probably isn't a lot of similarities. :-)
If yours is on a Ford F53 chassis, you may want to drive it a little bit to see how it handles, then do the Cheep Handling Fix (CHF). This is an easy change to the front and rear torsion bar links (they get moved to a different adjustment position)
Don't spend any money on other stuff to improve handling, i.e. track bars, steering stabilizers, etc, etc, etc do this first. You may find the CHF is all you need to do, and if you do it yourself, it won't cost you anything but about 1 hour of your time.
You can see how mine are done, Yours are very similar. This one item will vastly improve the "squirreliness" of the F53 chassis.
