(P.S. Dragonlady; I think you meant that you have to crawl under there anyway to remove the DRAINPLUG (not the filter), right? You can easily remove the filter from the topside as described in my original post.
I'm sure it's not a big deal to remove the skidplate. My consideration (and I'm speaking from a Manufacturing Engineering background) is that although you can remove the bolts easily enough, you "cycle" the threads of both the bolts & the fixed nuts everytime you remove these bolts. You also will lose a small amount of tensile strength (the bolt stretches so slightly) when you apply torque to the bolt and nut to keep them in place. I plan to change my oil and filter every 2500 miles, so by 100,000 miles I'd have put these fasteners under at least 40 cycles (just for oil changes, more if I have to remove the plate for a bottom hose or antifreeze changing, etc.). I'd bet that the fasteners aren't grade 8 hardware, either, so at 50 cycles I would expect them to start exhibiting some level of fatigue. The other concerns are; losing a fastener (meaning a trip to the hardware store for a metric bolt) or worst of all, cross threading one of them (9 fasteners per change x 40 cycles by 100,000 miles means 360 installations and removals of fasteners......might be pretty easy to cross thread with all those ons and offs).
Bottom line is all that can be avoided completely by removing the filter from the top vs. removing the skid plate/mud guard. And the reason I posted this as a helpful hint is because this method (removal from the top) seemed to be the consensus of a lot of Tundra owners when I read through all the oil changing comments on another site. It's why I decided to try it on my first oil change last week. Anyway, I thought I'd save owners visiting this site a lot of time checking that out. To each his (or her) own, of course.
All that said, I'm personally going to avoid both methods by purchasing a new 3/16" thick skid plate in a few months. This aftermarket plate allows you to access the oil filter from the bottom while not having to remove it.
