SuperSrpings Experience
Truck suspensions are all interesting examples of compromise. Stock OEM set-up for pick-up trucks is probably weighted in favor of grocery store runs; but for us TC haulers (especially in off-roa...

George,
I am happy you found a good solution, and so close to home.
How much does your camper weigh? I remember seeing it at Yosemite a few yrs. ago, but can't remember the details.
I have had similar good luck by just adding one more set of upper overloads (secondaries), Stable Loads, and the sway is very little; with or without the anti-sway bar attached. The anti-sway bar is a rear axle travel limiter with lots of recoil. You take the good with the bad.
Here's the way I see it: if you tighten up the rear axle springing and diminish the travel of said springs you will get less sway. The tradeoff is it limits the actual travel of the rear springs for going over undulating ground and getting your axles all twisted up. It puts more pressure on your front springs to do more travel. So, what to do? If there is a way to make the front springs more pliable (lower spring rate or graduated spring rate, or taller coils, in my case) and have a longer travel on the front to offset the rear axle, we might have something. This would allow for less frame twisting, which is, over time, the killer of tightly held TC' frames on standard pickup truck beds. Then, pulling on that string, you might have to have double shocks or remote reservoir shocks on the front to take up the slack, so to speak. I went all through this with my rock crawlers over a few decades of leaf springs trying to find the Valhalla of spring rates. I did find a greatly flexible set of front springs, but alas the tradeoff was a short lifespan. they will flex mightily, but are ephemeral.
