I think the "towing capacity" that Jeff is questioning is the GVCW. It seems the DOT in all states are becoming more and more stringent, especially since 9-11, and it's only gonna get worse.

As far as I know, there is no way to increase your GVCW, except to upgrade to a different vehicle. I believe it takes into account the drivetrain, chassis, brakes, and weight of the vehicle itself. The weight of the truck is one of those wierd little things, as often times the lighter truck, in the same weight/chassis combo, will have the higher GVCW. A good is example is like some of the gas rigs having slightly higher ratings than their diesel counterparts because they are lighter.

What is the GVW/GVCW of your SS454? If I had to guess, I would say you would be real close or a little over with a 20ft enclosed and your Z, but wouldn't have a problem with just an open trailer and your Z.
