>Scenario #1:  18 sheets of 4x8' OSB  on top of my roof rack(yes it's a
>stout rack system!)  Tires and suspension complained and I didn't drive
>very fast going home.
Scenario #2:  16 kayaks   8 stacked vertically(on their seamlines with a
built in support bar on the rack), 2 suspended underneath the rack, and 6
inside the van.  Also removed the passenger seat once and fit an 11'
whitewater play canoe inside and got the rear hatch to close and latch.
Scenario #3: 18 rolls of  R-19 insulation(I can't remember the last time I
had the middle seat in my van, maybe when I drove it home from the car lot
in 97?)
Scenario #4: 6 bales of R-30 insulation.  This was harder than any of the
previous 3.
