Rear Hatch Opening - Affected by Gobi Ladder??????

[SRFCASTR]

I had my Gobi rack and ladder installed and found the rear hatch opening sluggish. In fact there seems to be little if any hydraulic lift to it. The rack was installed immediately after I took delivery and do not know if this is caused by the weight of the ladder or a problem with the hatch hardware. Anyone have similar issue? It is NOT like dead-weight, but it must be raised actively to its top position.

Is there a way to adjust the "lift" of the hatch hardware??

Thanx
