The people with non trd yotas are too busy having fun and or working off the beaten path to post of videos of it. MY 2012 Reg cab I4 5 speed manual taco with open diffs has gotten me plenty of places. It never fails, you end up hours into the middle of no where get to a trail head and two things happen. A bunch of mobbed out jeeps and trucks show up and you see a stock subaru station wagon at the same trail head. your truck, those jeeps, and that station wagon all got to the same place....
Deep mud, snow, and the super steep loose stuff are limits, but I dont feel like beating on my truck anyways.
Pick the right line, and know when to back out if rolling solo and you will be surprised what a good set of ties will do for you. Short of a few steep and muddy trail sections there has never been a time where I wasn't able to get my tuck to a point off road that I wanted to where a locker and or the TRD package would have made a lick of difference. If you really want a locker you can add one for a lot less then the price of the TRD package. A good set of tires chains, and some traction devices with a shovel tossed in is even cheaper and will fix 99 percent of all problems with enough time.
The SR and SR5 are what tacomas are supposed to be. The TRD pro is awesome, but not fifty grand awesome. The way I look at it is all of that stuff is used perhaps 1 percent of the time, but its a whole lot of extra things to break and pay for. Thats a lotta gas money for getting off the beaten path and checking stuff out
