Before I answer that -- the other tool that's really handy is a heat gun. It's great for reshaping all that soft plastic.
But as far as the NEED for trimming goes: Your mileage may vary. But I did all that to run 285/70R17 on a 3" lift.
It just depends on your tolerance for rubbing, and how you use the truck.
But remember the wheel well doesn't change size when you lift. And the truck's only at the full lifted height when parked. Once you're on the road, hitting bumps, turning, backing up, the suspension is cycling dynamically.
And when the suspension's fully compressed, the wheel goes just as far into the wheel well on a lifted truck as an un-lifted truck. (exception: top plate spacer lifts. But that's a whole different discussion.)
I talked to one shop owner who didn't trim his customers' trucks aggressively - he just told them not to turn to hard-steering-lock to avoid contact.
Some folks would prefer that vs. taking off pieces of their inner wheelwell. Whatever. I suppose that plan makes sense if you're only going to have the truck a little while, and you plan to return the truck to stock at the end of a lease, or when you sell it less than four years old.
To each their own. I'd rather have fully clearanced tires. And the trimming is not obvious to anyone who doesn't get down and look INSIDE the wheelwell. Even then, folks who don't know what they're looking for usually won't notice.
