I had on my bucket list one of the toughest trails California has to offer called the Dusy Ershim trail situated up high in the Sierra Nevada Forest near Courtright Reservoir. The trail is 31 miles & generally can be completed in a fast pace 3 day journey. 4 other friends with 80 series rigs like mine did it in 2 days because of the Big Creek fire started the 2nd day so we had to bug out 21 miles in one day. Crazy.
Here is the ih8mud thread my friend started:
Got lazy & tried to push a few tress over. The tress won.
The undercarriage took most of the carnage.
the muffler took a big hit toward the drivelive.
The rear lower control arm hangers took a lot of big hits.
