Good read for P30 chassis
HereI had a P30 chassis for years and did just about everything to it ipd large diameter front sway bar with poly front and rear bushings,idler arm,super steer bell crank,super steer front coil springs,super steer rear trac bar,steering dampner,steer safe,Koni shocks,inner and outer tie rods,two sets of tires over the years and a few alignments and still hated the way it drove. I fixed it by selling it and getting a DP. :B
These chassis were made to be potato chip delivery trucks not rvs.
