I had the tag in 2019, you'll have a ball. Saw tons of elk and tons of bulls, had some great opportunities. My family has hunted it for many years for both deer and elk and we've pulled some good ones out of there over the years.
We spent 99% of our time running around in the Jeep. The Skyline Drive and other main-ish roads are almost good enough you could drive a Honda Civic through large portions, but there's enough crappy portions that the Jeep was worth it. Dropping into holes and off onto ridgetop roads that were less than bueno was a breeze.
I would say any type of transportation other than your pickup is a good idea. Having said that, an ATV won't be much fun if it's as dry as it's been the last few years. You'll chew the air with how thick it'll be with dust, I personally wouldn't wanna run around much on an ATV, but that's just me. I'm spoiled having our Jeep, I guess I've gotten soft haha.
EDIT TO ADD: Quality binos are a must out west, period. This entire unit lends itself pretty good to glassing. All the roads are on the top and everything is down, so it's easy to drive to good glassing knobs and locate animals in the draws below. But I can count on one hand the number of times I used my spotter. If you've got the coin, it's a worthwhile investment. But don't do it if you can't make it happen. I would invest in quality binos and a solid tripod.
