I thought this would be an easy install but it was a little harder than I thought. The lining up of the top bracket was easy. Once the ladder was hung and the top bolts tightened, the bottom bracket was almost impossible to put on. The ladder was sticking way below the door panel and the bottom bracket was not long enough to wedge into the bottom of the door. So I added 3 washers on the top bracket to bring up the height of the ladder, which helped a little. I then left the nuts loose so I could push the ladder up from bottom while I was placing on the bottom bracket. I had to wedge the left side(looking from the outside) so that it would move up level with the right. That was really hard to do while tightening the hex screw little by little since the allen wrench would hit the door after a quarter of a turn. The bar for the rear door wasn't much fun either.
Once everything was tightened I noticed that the ladder was crooked. I yanked it to straighten it and all was fixed. What an ordeal.
I think the design needs to be reworked in the following areas:
1. The top bracket is straight where the left top side of the door (from outside) curves down. This caused the ladder to sit crooked. The top bracket should have accounted for that by making the left screw post higher than the right.
2. The bottom bracket is way too short. It should have been made longer on the sides in order to take into account the overhang on the bottom of the ladder.
3. The metal strip that is supposed to be for the screws is very flimsy. The bottom bracket should be made so that there is a built in plate that moves when you adjust the screws. This sheet metal with double sided tape "plate" was horrible.
Other than that it looks great once it's on.
