I have a 16-20" tall plastic tool chest/step thing. Its an old one, I can't find it online anymore. This is the closest i could find (mine looks a lot sturdier)
I'm 5'8 and can't do jack squat under the hood of my 2015 Z71 without it. I can barely reach the dipstick to check the oil without standing on something. Makes me miss my 2000 Z71 a bit more...
