We are the 3rd owners of a 2007 Bounder / Model 33R on a 2006 Ford F53 V10 gas chassis and 22.5 aluminum wheels. At 45,000 miles  I'm not satisfied with the ride and drivability of this RV.  We have done front and rear alignments (rear was 1/4" off), weighted the coach (learning we are 4-5% heavier on the right side), replaced shocks with Koni, replaced tires with Michelin (balanced with Dyna Beads) and added Blue Ox TigerTrak rear trak bar. We may add a Blue Ox TruCenter steering control.  We run front tires  at 95# and rear 100#.

A "suspension improvement specialist" at the recent SEA rally in Brooksville FL said we could have saved our money by first installing aftermarket sway bars - a heavier replacement for the front and adding a 2nd bar to the rear while retaining the factory original  - there was a show special $1,350 installation. He claimed that this would significantly improve ride and drivability. 

Any comments on upgrading the factory sway bars appreciated.
