Love the idea of how much bigger they are to regular Wranglers and you much more you can care/do with them. I'm not sure how well the will handle the off road style most Jeep owners love about their smaller Wranglers, but it will still be used as such.
I watched the whole video and was amazed by all the options they built into the rig. TFLoffroad did an amazing job. From the low profile bunk, awning, pull out box storage, even a extra water can (or fuel) This truly is the JT camper, with food ready shortly! I searched, but can not see the build cost of the total options package.
You can't buy that rig, Jeep built it just for Easter Jeep Safari. It's a custom concept Gladiator to showcase what the new platform can do. Give the aftermarket a year to nail down some new stuff and you will likely see much of what Jeep did here available.
