If you have rigged correctly, two conditions exist:
In the down position and with the cylinder fully extended, there will be little to no force imparted to the mounting points…just enough shaft movement to have the gear links
go over center and lock.
In the up position, the only force on the mounting points will be the actual weight of the gear.
This is what you want to achieve. Otherwise, 12-1500psi applied to the attach points could cause delimitation/failure over time.
It’s no big deal to get it just right.

Nice work on the internal stop. My problem is that both you and Chris Z. tell me I "must" provide a down stop, but that's in direct contradiction to the instructions in the manual. If it's mandatory, then why no Service Bulletin? I understand that there were a lot of mistakes and omissions in the manual, but I'm wondering if there have been any instances of over-center links failing due to having down side pressure on them? Have there been any other actual problems, or is this just a theoretical "nice thing to do"?
