Rough Country leveling kit ($300 w/ alignment?) 6 years and 60k miles ago, and Jeep takeoff BFG MT tires ($400 for 5) for the last 20k miles. Lots of off road time and no issues.
Halfway up a mountain on rough logging trails, stayed the night in my off-grid cabin through a decent snowstorm, hunted, and slid my way back down the following day.
Bought my truck in April 2019, RC leveling kit went on the following month. 65k miles later and no issues or regrets here.
My truck is used off road about 1/3 of the time, hauling stuff up and down a mountain. Never noticed any limitations here, for what its worth.
2019 at 63k. Lots of off-road and work use, but not "off-roaded". Had transmission work under warranty but no other major issues beyond that. I plan to keep the truck long-term and bought a commuter car ('19 Fiesta ST / go-kart) to save miles on my truck.
I pulled stumps with my Ranger, while clearing a food plot on my property. Just have to use common sense and know when to say when. Dig around the base, cut any major roots, and pull slowly.
