Mark,

Looks like a great mod. Have enough road time with it enough to
comment on the change in ride/stability characteristics? I'd expect
more "floating" and rolling with so much lower pressure. That might
create more need for rear sway bars, which I don't like with the OEM
bags because of the leveling problems the heavy ones create.

Ken, unless the geometry of the suspension is changed, the ride rate should not change--it takes so much force to get the coach to the correct trim no matter what combination of area or pressure you use--again, assuming the bag is in the same place with the same lever arm relationship,
