Good grief. The power train is heads above the 3rd gen. No more gear hunting and the torque nearly reaches that of the naturally aspirated V8 Tundra engine. It pulls my camper much better than my 2016 Taco. I've driven trucks since 1985, and the suspension is fantastic. I've never seen a truck...
These prices take me aback. I PPF'd the forward-facing metal* portions and the top of the rear fenders (under my cap's side doors) for about $150 using 3M's PPF purchased by the roll.
I didn't do the plastic portions around the grill–because they don't take a beating like the metal does–that's...
It's doable as a DIY project using rolls of 3M PPF available on Amazon. I did the same on my (then new) 2016, and it looked as good as the day I installed it when I traded it in last August.
There are plenty of good YouTube videos on how to apply it.
