Toyota Land Cruisers - Moab Utah - Poison Spider 

I was in the 100 Land Cruiser and it was on 33" tires with a rear air locker, I think I only used it once on Poison Spider. I don't believe any of the other vehicles were running front or rear lockers. I think you'd be fine with your 80 series on 35s, it is a fun trail!

Thanks I’ll definitely have to take it down there this year I do have a winch on it , Then make improvements along the way

That is the Dobinsons bumper. It's pretty solid but not the best for ground clearance.
