I just went out and measured ours and it's 14" deep at the bottom due to the wheels, the rest of it 12" deep and only 40" height. I didn't measure how wide it was because I forgot. But the listing is wrong. It's insanely heavy and we got it to replace our 2 wheeled one that is 30 gallon (I think.) After hubby had a heart attack, I didn't want him lifting it up to dump. This 4 wheeled one is fantastic! No lifting to attach to hitch or dump it. It's worth every penny if you consider that you can have a heart attack or ruin your back. You only have one body. One more thing I noticed is that we paid $40 less for it in February of THIS YEAR. It's crazy. RV item prices are going through the roof.
