Quick Google search showed approx wt of 4000 to 4500lbs for a '24 footer.
My hemi quad with 6.5 box and 3:21 gears is rated at a hair over 8000lb but jumps 2000lbs if it had 3:90 gears. It felt surprisingly good with decent flexibility even when towing a steel enclosed car hauler with the Cobra on board. Have added rear air bags (inside the spring style) plus pair of Bilstein HD's and run tires at max psi when towing.
