You deleted your original thread just as I posted a response...anyway:
Either the 865 or 866 sound like the spring to use to accomplish your lowering goal. With my rig and load the 866 didn't work out for me plus I am not a fan of "progressive spring rate design" but there are others here that like them. FYI: I ran the 865's for a short time when I had the AO drawer system with all the gear but with the factory rubbermaid bumper and the 865 was fine (until I added the Slee rear bumper with tire carrier). You may, for trailering, need to add air bladders to either of these springs...
