The only problem I had was the holes needed to be moved closer together. As the unit is being deployed the distance between the holes increases.
There by over extending the strut length. I had to shorten the distance between the holes by 3/8" to 1/2". It wasn't much but now it works great.
Unlock and deploy the unit, check the distance between the holes over about the first 10" of the lift from the stowed position. Other then that
the instructions where great.
