I started out with an aluminum tripod, then steel, and finally JT Stabilizers on our last rig. The tripods did nothing, and most of the time stayed in the truck because the campsite was uneven and the tripod was too short or too tall.
I only wish I would have put the money I used on the tripods for the JTs in the first place, would have saved time and money. When set up correctly, the JTs were more solid than my current 6-pt leveling system.
Here is another thread just started from a guy that sold his tripod and installed JTs
