Yeah, that is my rig, I call it Wuggy. Thanks for the compliment. I am very impressed you made it up with ease but Toyotas are bad ass. Had some buddies back home with FJ40s and they went places. They just seem well balanced, the truck is set up the best for that obstacle IMO.
What air pressure were you running?
When we went, rigs with the lower air pressure ~15 or lower made it. All guys running Toyo MTs were denied but also had shorter wheelbases.
Just curious what worked and what didn't. My buddies built Bronco (locked front and rear, doubler etc) had a tough time and ended up seeing a rope before getting over.
We should check out Guzzler canyon sometime this winter. It washed out pretty good and is close to town.
