How much payload are you talking? The JTR has 1200lbs payload (give or take 50lbs based on options) vs 900lbs for the JLUR. That's already with lockers, off road tires, steel bumpers, armor, sway disconnect, etc. The JT Sport S with max tow package has 1550lbs payload (also give or take 50lbs). If you start with a Sport S max tow - which has the upgraded rubicon dana 44's minus lockers - you can pretty heavily outfit it without running into payload limits. Even a JTR with 1200lbs has quite a bit of payload to work with given it already has almost all of the off-road goodies you need. Mine has 1148lbs payload, reduced to ~1050lbs when you factor in the winch I added - the only 'modification' I made. With the wife and kids on board, I still have 600lbs of payload to work with - that's just for camping equipment and supplies as the vehicle is already fully outfitted for almost anything. My (admittedly huge) tent weighs 160lbs, camp stove and fuel is 20lbs, full rotopax with extra fuel is 30lbs. My camp bag duffel, which contains everything I need outside of the above, is another 100lbs. Figure another 100lbs of BS. That still leaves 200lbs for food and water. With the JLUR, it'd already be 100lbs over payload before adding supplies. If I'm compromising significantly, I don't know where. The JLUR is marginally better off-road, so there's a slight compromise there (and I had both and can verify it's a marginal difference).
The only other vehicle that's close is the Chevy Colorado Bison, but it's 2000lbs short on towing capacity, and as I regularly tow my airstream the JTR was the better choice. Bison might be better, depending on what options needed, as payload is only 100lbs less than the JTR and towing might not be a concern.
