I bought the 30x16 version. It fits my 15-passenger Chevy van. It was just large enough. I removed the hood and painted it in the booth at the same time, which was tight. There would have been much more room if I had painted the hood on the van instead, or separately, but this eliminated the wet edge problem on a large vehicle. I also had two platforms in the booth to paint the roof. I used the smaller motor to inflate and the booth and the larger one to evacuate it. The evacuation was adequate. The built-in filters did a good job with particulates, but the fumes still filled my shop, so a respirator was required everywhere. This spray booth would benefit from many more strap loops on the inside for hanging lights. I'm satisfied with my purchase and will be using it from time to time in the future.
