Toyota Trucks: Bouncy shocks

Hi,

I replaced the worn out original shocks on my T-100 this fall. I had seen a
lot of rancho on trucks around town, read about them on the internet, and
thought they would be a good replacement shock. I put the 5000 on the front
and 9000 on the rear. I thought having an adjustible shock would be a good
thing, since I sometimes tow a camper or a boat, and of course, the bed is
sometimes empty, sometimes, full. I discussed this briefly with my 4x4 shop
and they thought this was a good arrangement. I am very disappointed, the
truck now often seems to seesaw down the road. I have tried adjusting the
9000, but have not yet found the right combination. I have tried putting
sandbags for traction in the back, but it doesn't sovle it either It gets
very annoying, and I can't imagine it is good for the tires. Anyone had
similar experience? Was I a total fool to mix the 5000 and 9000? AND, If
the answer is yes (to the fool part) what is the best course of action?
Has everyone else been happy with their ranchos?

THanks,
