This topper came off of a 2018 nissan frontier and the person I bought it from had it on a toyota tacoma. The back window is broken due to me flipping it up to load trash in 35 below weather. There is a brake light on the inside of back window. Not sure if it works never had it hooked up. W 57in L 62in H 22in (give or take. I'm not great at taking measurements)
