After having a skid plate drop on my chest, I found a larger style floor jack makes the install/uninstall very easy if you get the jack centered on the plate.
I'm tempted to take some pics of my skid plates... I could see some definite scrap-age in several places after my 2009 Moab trip. I really got the skid plate to protect the low hanging transfer case, its the last thing you need to smash across a rock while on a 4x4 trail.
