Actual rear axle weights depends on several stds and options....age of truck but many who have weighed their late model one ton DRW trucks weigh in the 3500 lb range as it comes from the factory.
Then some folks rig their trucks like they want it with aftermarket products and then weigh the axles. It can be quite a difference.
I've bought several LDT's (mostly one ton drw) and put them in commercial service pulling heavy equipment trailers/etc. I always loaded things up and made a trip or two and then decide if air bags or other type of rear suspension help is needed. Some trucks needed help and others didn't all depending on year models... bed or wheelbase lengths.... 2wd or 4wd/etc/etc.
