Good choice, I think it will do all you need to do! We are going with the Rubicon with most all options, I will remove the rear seat and built a box to add more secure storage in the cab. Are you looking at the Rubicon as well, what options? How much lift and how big of tires are you thinking? We are probably going 35's with a leveling kit.
So this is really an interesting question. We've done a metric ton of research for our global overland build. One of the things we've learned from folks who have gone before us around the globe is that there are some significant differences for building out an overland rig for North America vs a lot of the rest of the world.
I actually wrote an article on the topic should you care to read it:
How To Avoid Mistakes In Your Global Overland Build
If you read the article, you'll note that something that I harp on quite a bit is payload capacity. I also talk about tires in that article.
The TLDR version is that if we were building out a rig just for the USA, Canada, and Mexico we'd build it much differently than we are looking to build our next rig. But since we're looking to drive around the world, a ton of other considerations come into play.
I wanted a Rubicon, on 37's with a 3-3.5" lift and 1-ton axles. (That's the Jeeper in me coming out) but the payload capacity on the Rubicon trim is actually one of the worst in the JT line. It took a ton of research (and basically a direct contact at Jeep engineering) to track down the configuration for the "RIGHT" JT package for us. That is with the cornerstone of our build being the payload capacity (and still wanting to run a Jeep)
So what we've learned is that the Jeep Gladiator Sport S with the Max Tow Package with a standard transmission has the highest payload capacity you can get on a Gladiator at 1700lbs.
But with as many road miles as we'll be driving, we really don't want a standard transmission. (Though in truth we're still considering it as we don't purchase the vehicle until January.)
So with an automatic transmission the highest payload you can get is with the same trim. So JT Sport S with Max Tow Package and auto transmission gets you 1535lbs of payload capacity.
Compare that to a stock JT Rubicon which I believe has a payload of 1200 lbs. That extra 335lbs makes a HUGE difference in what we can carry on our journey.
Also you mentioned the tires. Well, larger tires also adds more weight that the rig is moving, and they aren't easily sourced in much of the world.
@Dan Grec of The Road Chose me
did an excellent video on this topic, and he has the "overland cred" to really make such a statement.
So believe it or not, we will be looking at getting a Jeep Gladiator Sport S with the Max Tow Package and automatic transmission, and we'll keep the stock sized tires. I'm thinking we'll opt for the 2" mopar lift from the factory (even though it will make it look like a roller skate) and we are looking at doing a 60 seat delete as well. This will help in the distribution of the weight in the vehicle when loaded.
Our current vehicle which we'll be keeping in North America is a JKUR on 35's with a 2.5" Rock Krawler lift. It has been very capable and given us very little issues. But it is not the right vehicle IMO to travel the globe with a family of 3. So we're building out our new one, which I'll be updating here on this thread as we start making progress.
Hope that all makes sense and answers your questions. Thanks for your continued interest in our journey.
