Hi All! Just purchased my first toy rv! 1991 dolphin in decent shape 100k. Long time waiting, finally pulled the trigger. I want to do everything on the under carriage. Shocks, new air bags, tires etc... But I'm turning to y'all for the real insight.. Thinking new bushings.. but which ones? And what else am I not knowing? And where to get preferred parts? And upgrades? Looking for any parts list or advice while it's up on the rack! Thank you all so much !
