Cobra trailer stuck closed
With zero pressure in the struts, you've got to lift the whole weight of the top and it's heavier than hell!
It may be worse than that: If the piston seals failed but the rod seals held, all the gas pressure is now on the annulus or ring-side of the gas spring thus keeping the rod from extending swiftly. Applying up-pressure on the lid and then waiting may do the trick.
Good luck!
