You need the curb weight of your Jeep, not the GVWR.
Curb weight or
Unladen mass is the total
weight of a
vehicle with standard equipment, all necessary operating
consumables (e.g.,
motor oil and
coolant), a full tank of
fuel, while not loaded with either
passengers or
cargo. I am pulling a 2014 Jeep Wrangler Unlimited (4 door.) Curb weight is around 4200 lbs. I have a 5000 lb hitch and use a Blue Ox tow bar that I picked up from Craigslist. It is awesome. The arms of the tow bar move in and out and lock into place when you pull forward making hook-up very easy.
