Lorry,

Thanks. On the tire pressure suggestion, turns out that the max pressure
for these tires is only 35. I've always been one to run near the top of the
recommended range; I like the stiffer ride and it seems to help gas mileage
noticeably. In this case, even running at the max pressure, it's obvious
that the sidewalls aren't stiff enough.

Looks like another trip to the tire store is in order...

Hi Erik,

One way to improve the situation you
describe is to signifigantly increase your rear tire pressure (36-38
psi) and also the pressure of the trailer tires (40 psi). To get a
better feel for the situation, try pushing the rear of your vehicle
sideways with a pulsing effort.
