I've posted this before but everyone should know how to manually operated the slides before they buy the rig.
I was confident I knew the procedure on the current rig. Then the hydraulic pump leaked and ruined the motor. Lipper had 3 design problems that prevented the manual procedure from working and when pointed out they sent me a upgraded replacement pump.
I'm not sure that it's possible/practical to bring in my heavy slides by disconnecting the hydraulics. And if so what would keep the slides in with no hydraulic pressure? I suppose one could build a stout frame setup inside the rig to block the slide closed.
