Im Steve 32 USAF veteran residing in Phoenix AZ 3 kids living full time out of our toy hauler this is my 2021 sierra 2500. No real suspension upgrades yet just got my torsion bars cranked to level the rig out. 33” tires looks TINY and I’m thinking of going 35’s or 37’s. I have a whole route planned to Prudhoe bay Alaska. Starting from my present location I plan to hit multiple national parks. Grand Canyon, Zion, Capitol Reef, Canyonlands, Arches, Bryce Canyon, Crater Lake, Redwood, Yosemite, Death Valley. Don’t know when my start date is but I’m hopeful it will be within the next couple of years.
