One comment on "rear steer"... the middle wheels are prone to "rut steer", and can be a handful if you drop the rear wheels off the edge of the road (if there's any kind of lip).
The rear "trailing" bogie will just dutifully follow along, but the front one, mounted on a "leading bogie" (with the tire in front of the pivot point) is prone to flexing enough to cause a steering motion (always the way you don't want it to go). On my coach, this wasn't ever really a problem, but was very noticeable on interstate with pronounced truck ruts. And if I did drop the rear wheel off the edge of a lipped road, it could get downright "interesting" as I corrected (as the middle wheel flexed enough to send the rear of the coach moving the opposite direction until the force on the tire was enough to pop it up over the lip on the edge of the road).
I installed a set of the True Track devices on the middle axle bogies, and all these bad habits vanished (they keep the lateral deflection of the middle bogies to a few mm's).
