man whats a 3 link? is that a 2 link with panhard?
If you claim mini trucker, I dont think you'll need more than a 2 pump setup. yes hydros are reliable. its the same stuff used on airplanes, why wouldnt it be? I hate some of the 'stereotypes' with juice.
about running coils, I wold run coils in the front. dependin on your wheel size those trucks can lay crossmember pretty easy. just need deep cups. But if your on big feet and start running out of coil,you could problly find some drop spindles or control arms for that truck.
Also being a mini trucker, you might look into shock relocators for the front and accumulators for the rear with 1/4 - 1 ton mini coils (sorry I can really recommend if your using accumulators, But I would think you could get away with some softer coils (with enough turns) and 'lowering' shocks in stock location.
The only thing unreliable is when some guy borrows his dads arc welder and welds flat 1/8" steel to the side of his frame and calls them spring perches. ghetto stuff like that is where hydros get there bad rep. Its not gonna break down any more than the similar components the rest of your truck is compromised of and when things do screw up, they usually dont leave you totally stranded.Even with a blown pump seal or a run away pump you can still lift the car off the ground to drive it home.
