I guess since this thread has been bumped, we should include Jeep's Stitch build.

Carbon fiber hood

Obviously most of this doesnt justify the cost but worth mentioning.

This is one of the reasons I've never installed a winch, even the lightest ones are pushing 100LBS unless you get a comp winch, plus you have to add a bumper or at least a winch plate.

I stubbied my stock front for free, added the Teraflex aluminum sliders to replace the stock Sahara crap and a Poly crossmember skid combo to replace my tacoed stock crossmember. My 4 dr being light helps me out a lot compared to the more heavily armored rigs in my club, I never ride alone, so let my buddies use their winch on me if I get hung up. :D

I also don't pack up to heavy when on the trail, usually just a cooler for drinks, and snacks. Keep all your spares back at camp with the doors, but i'm not out in the middle of no where either, just an ORV park where im not far from "base".

Don't mean UV protection for the interior although that is a consideration as well. I meant is this thing going to turn into a foggy mess after a couple of months in the sunlight like really old headlights.
In the JeepForum thread, Optic Armor comments quite a bit. Give that thread a read as they have answered a lot of the typical questions.

By the way, I updated the OP with TOTL's hood.

I'm surrprised now one is sharing to their over all Jeep weights.

I know this is older but maybe this will respark some interest.

I was at 5080 with the doors on. No top. No back seats. And about half my tools.

Cage and 1 tons on 37s. ( To broke for 40s after the swap )

Are you saying that you were already on tons and weighed 5080? Because that seems quite low...

is it a safe assumption to say you have no spare, no carpet or rear seat ,winch/ hi-lift ,in the Jeep as-far as your definition of " bare bones" goes?

It took massive trimming and work and aluminum to get my four door w full size spare and all recovery tools to weigh under 5000lbs so I'm very aware of what is involved in "getting them down" per se ....
I'm trying to imagine , further, wtf I'd have to lose once I upgraded to 1ton axles to still come in at 5k lbs....
