So we've been wheeling in Utah the past week, around Canyonlands NP, Moab, and Capitol Reef NP. Mix of 2-5/10 trails on OnX.
Most insane was the very wet, South Draw Trail road heading out of Capitol Reef NP to Dixie NF, rated 4/10 when dry. Last 10% was a very narrow, gnarly hill climb on the side of the mountain that is completely washed and rutted out. It had been raining for a few days prior, so it was super-soft (where it's not recommended to do this trail). Had to commit the entire way up once choosing a line. It's so rutted that people have gotten bogged going down it from Dixie. Usually I'm not sketched out but doing this with 9" of ground clearance on 33's is a lot different than a Jeep Rubicon on 37's.
We survived, the line I chose held in 4L, rear locked, and 2nd gear pinned, and so did the bumper. We actually got closer to getting completely bogged on a section rated 2/10 in Dixie. Small creek crossing and two seemingly innocent puddles, checked the creek crossing and it was firm, but the soil where the 'small puddles' were was super, super soft. Again, 4L, rear locked, and 2nd gear pinned, land cruiser sideways rocking the wheel to inch out of that one.
After that we went to Sand Hollow State Park in Hurricane, UT (Matt's Off-road Recovery location) and drove in the dunes. Very fun little trip. Took it easy after and did a 3/10 trail to some Dinosaur tracks.
Bumper is still holding on, no bolts have fallen off, and other than that minor adjustment I haven't touched it. We've logged around 80-90 miles off road.
