I plan to take a trial run for pulling, my tranny is supposed to
deliver 220 ft/pounds of torque so I am trying now to determine if
that is suffiecient to pull approx 3000 lbs or not.

It's not ........... 220 ft/pounds from the transmission is not what you
will see at the ground from the rear end and that is what counts. Keep
in mind that torque also has to move your vehicle. As one person
pointed out you may have a problem just getting up a ramp. Just my
opinion but I think you are setting up a disaster looking for a place to
happen .............. good luck.
