Update: replaced the bad tire and drove my Tropi 60 miles to large truck tire & alignment shop for alignment. They said it needed ball joints, but reluctant to do it as no previous experience with type of suspension on my Tropi. Called another RV dealer who suggested I contact Chevy dealer who works on heavy trucks (& workhorse motorhomes?). What a logical suggestion...why didn't I think of that? Another 60 mile drive in different direction and $130 to diagnose. Told me it needs everything...ball joints, tie rods, air bags, steering damper....only $5k for parts & labor (ouch!). Hard for me to believe my 80k mile rig needs everything replaced. I wonder how common this is for P Series motorhome chassis?
