In AZ, anything towed over 3,000 lbs has to have brakes. Not only will a trailer + you TJ weight as much or more than the truck, it'll be way over the 3k requirement. If you were to be in an accident while towing, even not your fault, good chance your insurance would deny coverage if the setup weren't up to legal requirements.
I'd definitely look for a trailer with electric brakes rather than inertial and install a controller in the truck so you can set up the trailer brakes to modulate to your preference and driving conditions.
Thanks! I know so little about towing. Just getting into all this stuff. I think what I was seeing is a lot of trailers have brakes, it just doesn’t say it in the description on marketplace so I was assuming they didn’t have them, but looks like they most likely do.
