Ok without getting into a long explanation I agree that the zero degree is not a good candidate for that kind of work but I also have to say that it's not for the reasons you would think.
Typically, a container is going to spread the load evenly even if it's contents are loaded a little off kilter so the issue of the load bearing down on a single point doesn't hold water. The only issue here would be to have the bulk of the weight aft of the rear wheels reducing steering axle weight and creating subsequent loss of steering control concerns.
The zero degree is probably better at carrying a single point load (like a forklift or a roll of steel) than other beds if you can get them loaded (and that's a big if). The way the bed is designed, the entire length of the bed sits on top of the frame rail evenly distributing the load across the entire frame. On other beds, like Centurys and Jerrdans, the load may be carried at only 4 or 6 points where the slip pads hit the frame rails. This would create a situation where you are carrying the load at 4 or 6 small points creating unfavorable stress points that can bend or break something.
Having said that, loading a zero degree from the extended (flat) position creates it's own concerns for two reasons. #1 and the most important is if the load is too heavy, it will strain the connection point between the bed and the lifting arm & #2, the rams may not have the power to overcome the weight to lift it anyway. I can tell you from experience that the bed will lift 8000lbs from the lowered position but it will struggle to do it. Loading a Porsche Cayenne will show you this as that vehicle weighs in at nearly 8000 lbs.
On the other hand, the zero degree does very well, and in a lot of cases, better than a conventional bed when loading from the tilted position. When we load a 1 ton dually, we set the bed where it just touches the frame rollers, winch the truck up and secure it with conventional means and the bed can then very easily overcome the weight because all it has to to is fulcrum the load into the loaded position without actually having to lift the weight. If you could find a way to easily drag the container up the bed in this position, loading it from that point would be a no brainer.
Again, I would never send my zero degree after a container as it's just not that feasible when there are so many other ways of carrying it that are far better suited but it could be done if you really had the desire to think it out. Large skates that would allow the bed to slide easily would be one solution.
