Had a glance at the Wrangler yesterday. The comments re protection, axles etc apply to the base model. The top-of-the-range model has an improved drivetrain including lockers - at almost $10,000 more than the base model 
Can't say I ogled the chassis, but it's not rated for the same towing or carrying weight so stands to reason it would be less strong. Might not be less durable, though, provided it's properly engineered.
The Wrangler is a vehicle that, like the Defender, can trace it's design directly to the WWII Jeep. It has moved with the times, which necissarily includes a more "recreational" slant, and the same can be said for the Defender. Where it differs, however, is in the continued value of some of the simplicity of design and flexibility of roofing/seating/doors etc which seems to elude the evolving Land Rovers.
If Jeep can go to the trouble of extending the wheelbase of the Wrangler after 60 years of civilian Jeep design, then there must be a market for vehicles something like the Defender. The question is how Land Rover can capitilise on it.
