Just got back from a week in Moab, a trip I have been doing for 21 years now. Among other trails I did Hells Revenge, Elephant Hill, and Jax Trax.
To review, my GX has a 2.5" lift and 265/75r17 tires, and a factory trailer hitch, and the front fascia has been trimmed. I can now tell you that IMHO the approach and departure angles are not really adequate for these kinds of trails.
I have decided life is too short to suffer with inadequate clearance, so changes will be made... as soon as I figure out what they are. In my initial thoughts I'm thinking skinny 34-35" tires, regeared appropriately. This of course leads to a host of other changes, including BMC, possibly new wheels. I am undecided about lockers, but probably will get at least a rear locker while regearing. I will need to carry a full size spare somehow, and I hate the idea of bumper swingouts in the way every time I open the rear.
Bumpers front and rear may follow, maybe a winch since I will have the platform to mount it. Any rear bumper must include a way to integrate a hitch receiver into the bumper to improve departure angle.
Yeah, I had a lot of time to think about these things on the long drive home.
I'll head over to the 35" tire thread and start my research in earnest.
