We dont have any for trench rescue but we use Junk Yard Dogs for MVA's.
We have the struts and the screw jacks they work real well.
We just picked up the Res-Q-Jacks. Haven't used them on an incident yet but heard good things about them.
Ya, thats cool! What kind do you use? I have used Rescue 42's before and liked them alot too.
Res-Q-Jack and ParaTech Rescue Struts
We also have a set of Res-Q-Jacks and are pleased with them.
