I've had a Fumoto valve on my Sierra for last few years/70,000 miles. The drain on the pan doesn't stick below the undercarriage so the odds of something hitting and opening it are pretty slim. I installed mainly so I could attach a hose so I could drain into a container easier. I usually change the oil when it's warm. When using the stock drain plug, oil would come out fast and shoot way over to the side. You would have to have the drain pan really close to the plug or the oil would miss and make a mess. Another nice feature of the valve is it makes it much easier to draw a sample for analysis as you can open the lever just a little and fill the container up slower.
