Grant, The design has held up well. The only mods since construction (and which I need to document) are that I added upper stops to the swingarms. This prolongs the life of the springs which were getting distorted due to repeated bottoming out of the suspension (due to my habit of trying to drive over anything at speed). The stops consist of short pieces of fiberglass rod added to inside the suspension springs. The rods were an expedient and if I were to build again from scratch (or during a major overhaul) I'd probably use an aluminum bar bolted to the outside of the hull that would stop the swingarms on the upper arc. Even with the stops the springs still get bent out of shape over time so order extra ones when you finalize on the springs that work best. The non-precision flanged ball bearings I used for the hull side of the swingarms have loosened up a bit since first built, thus the arms have a little play side-to-side, but everything still works well.
Overall I'm very happy with the way the design has worked out and would use it again in another tank.
