If you don't have to lift it, don't, even on a non-lofted truck access is pretty good just rolling under.
If you do want to lift it, a proper LR bottle jack is often better(from the axle tube), though nothing to stop you using a trolley on the diff pumpkin, as long as it has a reasonable footprint, and not some cheap nasty thing.
Then axle stands as required, again on the axle tube, normally, though you can put them under the chassis if working on suspension that requires it.
