I went to the Bend Pak site and hired the installers from there. $800 and that included the 5gl of oil. They started around 8AM an finished around 1. I'm not on site, but is sounded like all went fine. They told me what when I use it, bring the car up past the locks then to the height I want then lower it so it's resting on the lock. This stops the lift motor from holding the pressure and an early death.
