The Camo eze-lifts have minimum height of 19" to 47" and fine adjustment to 61". 5000 LBS support, but I don't know how much you could actually lift without galling or stripping the threads. Good temporary support to remove and repair the jack. Maybe not enough to lift it to load into the truck and fix the jack later. So you may have to do the two diagonal leg slightly higher trick to be able to lift it with the eze-lift (I'd put anti sieze on the adjuster thread).
If you really want to lift it high enough to fit into your truck I'd call Rieco Titan and have them drop ship a single
Tripod Camper Jack . It has a minimum height of 38" and max of 60" and can lift 2,000 lbs. Only issue is the height you'd need for your 4x4 DRW truck, may need a block or two. One other consideration is that with the dually, you'd need to make sure that the tripod legs were capable of being oriented so you could avoid hitting them with the tires when loading.
