Did they switch to this at some point or was it an option?
Thanks!

That's the only setup Quigley has ever done on the Fords. I'm not a huge fan. Conceptually its fine, but the execution leaves a lot to be desired. Plenty of threads on here about the poor ride and handling quality of the Quigleys. Basically, it doesn't have anywhere near enough bump travel, and the angle of the trailing arms means the axle has to push forward during bump, just like forward-shackled leaf springs. Once the setup has any sort of wear in the bushings (which is inevitable because of the inherent binding), death wobbles ensues.
Not all is lost though. Better shocks and taller springs (ala Agile Offload RIP package), as well as upgraded bushings can makes it behave well enough. But why not just do it right from the start with a QuadVan?
TTB definitely has the best ride out of the box, since it offers more travel for the same right height. I did test drive a TTB and SuperDuty-based solid-axle QuadVan back to back, and was surprisingly impressed with the solid-axle setup. I think there's more potential for good high-speed off-road tuning with TTB, but its components aren't as robust as the SuperDuty's Dana-60, and I prefer solid axle for towing very heavy loads. If you're just doing old-fashioned rock-crawling, than setup with the most travel will generally perform the best regardless of spring or linkage type.
