Comparing "light trucks" (yes, 1 ton and under are light trucks) purely by payload and GVW numbers is like comparing a male to a female. They may have the same capacities but they are built different.
As an owner of a 1/2 ton and a 3/4 ton that set side by side in the driveway it's easy for me to visualize. I have friends with one tons and larger and I've observed those differences. I'd urge anyone yearning to tow near max capacity with a 1/2 ton truck to drive to a dealers lot and park beside a higher rated truck. Crawl under them and make a comparison and "see for yourself" where the differences lay.
