90% of the way down the "Headless Horseman" trail at Paragon on Saturday, this happened to a Ranger riding in the same group as us. Using the aid of 3 hi lifts, a bunch of guys to steady it, one jack stand, 2 tires, and some misc trail tools the truck was able to limp off the trail(being towed by another ranger). We never found the second lift block, so who knows how long it had been gone. All of the u-bolts were bent. On the passenger side, we were able to tighten the nuts down(thankfully they had a ton of thread). On the driver side however, the u-bolts were badly bent so it wasn't happening. Ended up only getting 2 nuts (one on each u-bolt) tight. So, how are you blocks working for you again?
