I have a tag-along question to this topic, specific to the Equalizer WDH and 3500 rear air suspension and hope you guys can help. I tried to ask Daniel Hicken at Progress Mfg. (Equalizer) but my email has bounced back. Maybe he's no longer there? That would be a shame.
So my basic understanding is that the Equalizer limits sway by the friction that is placed on the carrier brackets from the bars when they are "lifting" the rear end.
If the rear end needs no lift because of the bags being able to support all the weight, where does the friction come from? I can see this being an "issue" with a 3500 to begin with since the suspension is so stiff, let alone one with load-levelling air suspension.
Might cause more trouble than benefit you think? I do really like the idea of levelling a heavy payload if necessary, as well as the more compliant ride when empty.
Thinking of ordering a 2015 3500 to replace our 2010 1500.
**I did notice, however, that in the technical information on this suspension option that it has two modes -- payload mode which will self-level a heavy load and trailer tow mode which merely drops the rear end about an 1" - 1.5"....but does it then not level any more? Who knows? And what's the point of that? Isn't that what a drop hitch is for?
