Recommended improvements, in order:
1. Alignment, maximizing caster.
2. Big front anti-roll bar. I have a Hellwig.
3. Shocks; was a Bilstein fan, but was not really satisfied with how floaty the digressive valving was on my lightly loaded E450 chassis. Replaced those on the front with a pair of Monroe Magnum RV shocks, for silly cheap $$ from Advance Auto Parts. Really locked the front down.
If I hadn't spent the $350 on the set of Bilsteins, all that would have run only about $400. Aside from the alignment, did all the work myself.
