I rated this 4 stars for 2 reasons: 1. The steel is very thin and will dent quite easily, so once installed, so you better buy a rubber mat. 2. Instructions are ok, but use the MadJax video for installation. Box size is plenty big enough.
Very well made. Everything fit well and hardware was included. Just read the directions first to the end and it’ll save you an extra 15 min. There are included spacers for some models but there is no mention of them until after the last step.
