How many miles is too many?

I know this may be a loaded question. But how far do you think an 1XP will go without too many issues?

I drive it more like a Jeep than anything, I’ve been rock crawling in Moab and other places, but mainly drive on on two tracks.

I’ve got over 5000 miles on my 14, doesn’t use oil and no leaks, bushings are still good. I replaced the lower a arms because I hit a ditch too fast and bent them. Also one front axle I bent when I got stuck. Other than that no issues.

Soooo, under my conditions how far can I go before I start having major issues? One of my riding buddies got 5900 on his with no issue before he traded his off.
