I highly recommend the NSA ReadyBrute Elite towbars with built-in ReadyBrake! They are rated at 8000 lbs, and I think you will find the combination to be hundreds of dollars less expensive than anything else out there!
I would also go with the NSA break-a-way kit!
Good luck, happy trails, and God bless!
