I'd wondered how much roll articulation your Euclid has, and probably same for the Tourna-rock trucks? Either looking at it like axle angle, or tire lift height & wheelbase distance?
Looks like the Wooldridge gets almost 3" vertical tire travel, but i haven't started straightening everything on that yet.
So if a Terra-Cobra Wagon has the Walls slide off the Floor to dump, then what's a Belly Dump?
