I just looked up the curb weight on the Gladiator. Mine, as a Rubicon, is 5050lbs. I have added a front axle disconnect, lightweight steel bumper, some lighting, a light weight winch (about 56lbs), an AEV 2.5 Dualsport lift which might have added 50lbs, as a guestimate with taller springs and some brackets...I wouldn't be surprised if it was less....And then about 15lbs per 35" tire, so another 75lbs there (unsprung). There's a tonneau that probably added 20lb. So I am probably sitting at 250lbs added weight. I'm guessing 5300lbs vehicle weight.
Stuff adds up quickly, so that's why I like a ground tent, small 12v fridge (35qt), 550 watt hour battery, and basic camping gear. The Hi Lift jack only goes if nobody else in the group has one, if I am by myself, and depending on how difficult the trails will be. Mostly, it stays home.
My Wrangler is set up the same exact way. Most of the time, in a group, I believe I have the lightest vehicle among those lifted and modified. I think it is important for many reasons....fuel economy/range, easier on the suspension and drive train components, less tractive force is needed to move it or get it unstuck, better road manners/handling, and without a racks, better visibility, lower center of gravity, and I can drop the top or open the Sunrider for more fun and better views driving through canyons.
I find it interesting that there is a major trend among the big YouTube overlanders to now try and lighten up their rigs. I don't think they are just looking to make new content, but they have come to realize the advantages.
I learned this stuff with my 93 YJ Jeep that weighed only about 3,000lbs. It was amazing what that thing could do with only a limited slip rear end and 30 inch tires. And if it got stuck, most of the time it would break loose with just a push from a guy or two. Try that with a rig pushing double or more the weight. You can't do that even with my "light weight" JL or JT. There would not be a prayer with some of these monster rigs I see.
That little YJ, btw was a neat setup. I had 2 inch receivers on both ends and a cradle mounted 8k Warn winch. I only carried the winch and its weight when I was going wheeling. Not for daily driving, so that Jeep stayed close to its original curb weight most of the time. I kick myself for selling that Jeep every time I think about it, LOL. I used to "Overland" in it by throwing a tent, sleeping bag, stove, cooler, lantern, and air mattress in it.
I think Overlanding these days should be called mobile glamping. They've got satellite connections, diesel heaters, and 4 batteries with 2000 watt solar panels to power their cappuccino machines and recharge their vibrators. All that unnecessary crap to enjoy nature, except maybe the vibrators. Lol.
