Roy, I spent a while there, and some time today also, that website
does not seem to explain the difference. It lists very similar lists
of features. Maybe I missed something, in which case I apologize.

There is no difference other than rear springs and tire size. Same
chassis, brakes. axles and drive line. For than fact the 2500 even
used to come with stiffer rear springs before the 2500HD was launched
as they lightened the springs to make it ride better for sales. What
does this mean? Add a leaf or two to the rear and upsize to 265/75/16
tires and you will have a 3500 except for label on the door. As a
further foot note, I have a 2000 K3500 SRW (single rear wheel) and it
has the same GVW "rating" as a 2500 HD (9200) but it has more springs
in rear than a 2500HD does and will carry more weight without draging
its butt. GM uses one frame/chassis style for 1500 trucks and another
for 1500 HD, 2500HD and 3500. ALso a 1500HD has same front end as a
2500HD and same rear springs. chassis and drive line but it is only
rated at 8600 GVW (that rating is to get past LD emissions for 6.0).
Only real difference between to models is that the 1500HD has a 3 ton
rated rear axle and the 2500 HD has a 4 ton rated one (2500HD and 3500
SRW have exact same axle). THe suspension will make out on 1500HD and
2500HD long before axle 3 tons of weight is applied to axle though.
Both have same tires from factory. Thing are not what they seem if you
look below the surface. Check out this link
