ORI not lifting vehicle!!! WTH?

So I pressurized all four lower chambers to approximately 125 psi. Went around to the top started in the front with what we thought was 300+ pounds and nothing moved. Well that's weird. Move to the other side with 320 and nothing moved. Tried jumping on the front and nothing moved Llifted the front end off the ground set it back down still went back down to fully collapsed. Tried 380 pounds in the front on both sides nothing moves what gives

We went around to the back and got 2 1/4" with 350# ....should be several more inches at 350psi right???

A buddy told me to lift the entire rig at or above ride height and try filling the upper chambers again.

I did and that made all the difference!

It's sitting level in this pic I have an inch to go I think in front and back to get my full 6 inches of up travel.

Looking good!
