The addition of a Gorilla-lift kit made the trailer ramp easy to lift. Not a finger lift but more like 10 lbs. lift, but better than 70 lbs. lift without the lift.
Wish carriage bolts had a couple of options for placement because supports for trailer rail were in the way of current square holes. Bolts that came with the kit were too long for my trailer rail. Parts list and instructions show English measurements first then metric but should have only shown metric since everything was metric. Once installed so far no further major dislikes. Gorilla-lift was a simple solution for a heavy trailer ramp.
Right Gorilla-lift installed.
