I see. Makes sense.
I'm in the same boat as you. I'm just north of 110k, but mine is running like an absolute top. Chains were done a few years ago, crossover pipes were done last Spring. No reason to believe I couldn't get another 110k out of it.
Big difference between you and I is that I live in Kansas City and might make it to Colorado once or twice a year. In the interim, I feel a little bit showy driving around a vehicle fully kitted for off-road use that goes on road the full portion of the year. That's my internal struggle, not anyone else's.
But you live in Colorado and can maybe hit a great trail on any given weekend, weather permitting. I'd go for it if you have faith in your Lr4.
