All LD2500 are 8600lbs GVW. This means the most the entire truck can weigh
is 8600lbs. Your payload will depend on how much your  truck weighs empty
(with you, passengers, fuel etc) For example A 2wd will carry more than a
4wd because it weighs less empty. To get an accurate payload capacity you
will need to weigh the truck "empty" and subtract from 8600. I think you
will find about a 2200 to 2800lb cargo capacity.
