Does the FX4 package help much with towing and over all handling?
I've had both Z71 and 4X4 GMC's and I never really noticed a huge differance between the two.
The FX4 does have heavier duty shocks and other suspension components for "offroad" use. Those components are definitely a help while towing although when not towing you will get a firmer ride. I have the FX4 model in a 2007 and chose it because I felt that it would be better while towing and have been very satisfied with this model.
Once you add the 3.73 axle and the LT tire option to the trailer towing package you've got a great truck for towing. The LT tire option is a must because you can air up the tires to increase the stiffness, directional stability, and load capacity way beyond the standard "P" rated tires.
