I did some testing today, finally. The only nearby trail has a water feature that, on last measurement, was about 2 feet deep with soft mud underneath, so I hadn't been brave enough to risk going through it, but since it hasn't rained in several days (aside from this morning and some during the drive) I decided to risk it. Turns out someone has re-done the road entirely at that point, completely avoiding the mud pits. While is was good news, the "road" beyond it was a mix of decent gravel, rocky, suspension-destroying bounce-fest, and completely washed out. Driving solo (I'd prefer to have another vehicle with me but I don't have anyone with whom I can wheel around here) was a bit concerning, but gotta have faith in the truck and my abilities, I guess.
So, got a good 2-hour ride in some moderate terrain, and was able to completely flex out the suspension. The 2.5" Halos/Elkas handled everything pretty well, really, with only one bit of rubbing. Of course, just before the exit on what was supposed to be a one-way trail, the road devolved into a winding and narrow bobsled course, which I opted not to take until I PPF the paint. Queue backing up the trail for a bit... The second one-way route ended in a massive rock blocking the trail with a narrow escape off to the side that might have been okay, but I was concerned about making back up all that if there was something else blocking the road closer to the exit. So, it ended up being an out-and-back. I left it in 4H for most of the difficult part of the trip, but I usually wait for 4WD until the 2WD fails. It probably would've done most of it in 2WD, too, especially outbound, which was mostly flat or downhill.
OnX Offroad was super helpful on this as it hasn't really been routed before. I'll get to that soon. I should probably go in for another alignment tho... I also learned that I need more rear lift (scraped the hitch a few times) and better offroad lighting.
This screen capture doesn't really show the scale or depth very well, but this track isn't quite wide enough for the whole rig... I didn't get much still photography from this trip, so I guess I need to go back...
