From a destructive round of maintenance, here's what I did/had done to improve ride... Tires were already new'ish, but shocks, control arm bushings, ball joints, and front wheel bearings. Also had alignment, caster, camber corrected. Hard to tell what to look for without doing a ride along with you. And x2 on the 30psi being too low on the tires. I run mine @ 40psi, but I have a RCSB...
