OP here, sorry for the delay in responding, I was in the desert and out of Internet/cell range this past week. (My (Our?)favorite place?)
Jefe 4x4:
Agree with all you said; in my case the Outfitter Apex 8 scale weight comes in at an even (dry weight) 2,000#s; in my truck (Dodge Ram 2500, 2004.5 yr) the bottom leaf was sitting evenly across the the bottom overload leaf. My truck does not have upper overloads, which would've been standard on the #3500 model. Not much left to play with in terms of "gap"; the addition of an additional "layered" progressive spring constant was a necessity. The alternative was to build a new leaf spring pack; which I considered (and certainly and still a valid option) but in my case (IMHO) not as cost-effective as the Supersprings. Now, is my truck as "pliable" as I would like it? No. But again everything boils down to acceptable compromise.
My front (Coil) springs carry the Diesel option; so probably they are already loaded (or overloaded) compared to other options. Yes, in the future I will need to consider whatever suspension improvements reveal themselves. For now, I'm content to stick with my plan to upgrade shock absorbers; and see what else materializes....
Grodyman: No noise whatsoever.
deveildog1971: My stock truck with stock camper remains lower on the left side as compared to the right, by about ~1-1/4+". Does this bother me? Yes, a little. Can I adjust around it? Yes, if I want to, by playing with adjustment of my airbag pressure. If you were lucky enough (IMHO) to find a shop that understands this and knows how to adjust for it then I would love to learn about this; but my experience everywhere elsewhere is a bunch of blank stares and expressions. Open to any suggestions.....
