This Vevor Low Profile 20 gal Oil Drain Pan is a big improvement from the traditional drain pans (both big and small) that I have used over the years. It's pretty much eliminated the potential for spills while draining my vehicles or while transferring the used oil to containers that I can then take to recycling. It's LARGE so it takes up a good bit of space in my shop but it sure is handy, especially for the motorhome. The top edge sits almost 9\" above the floor, so it's not as low-profile as I need for some of my vehicles, although I typically have to take those up on ramps anyway to get myself underneath. The top of the motor is almost 12 1/2 inches above floor, so depending on how far the pan needs to get under the vehicle that can be an issue... but for a vehicle that big and wide (like a motorhome) clearance is probably not a problem. I like being able to roll this under my vehicles and not worry so much about drips or splashes going outside of the pan. And this pan seems built to last -- it's solid. I like it.
