I understand that the axle spacing for Alco tri-mounts is 6' 11" and 5' 7" from the middle axle with the bolster offset 22". What commercially available HO scale models come with this type of truck? From what I can tell, BLI's RSD-15 does, but I'm not sure about the other Alco's (c628, c630, etc.)

This would be for a kitbash project I have in mind which I'll talk about more later.

The Stewart Alco units have offset wheel spacing. Heck even the
Baldwins do. Those Rigid Commonwealth things.

The Overland U25C model has the correct Tri-mounts for the L&N version. Not sure if they are correct dimensional-wise but they look good running with old Stewart C628/630 models.

Haven't looked at them up close or with an eye for kitbashing, but what's under Bachmann's E-33 electric locomotive?

The most important thing is the offset of the axles on the trucks. Sideframes really don't matter since I'd be adding something that is heavily modified anyway.

The new Kaslo U-25C chassis has the correct trucks/spacing for the GE version of the trimount. Not exactly the same, but close.

...and isn't the trimount truck under the RSD series units, different than the one under the C628/C630? (Not counting the Hi-Ad trucks under the C636 and maybe some C630's.)

not exactly sure about the axle spacing, but the ge version of the trimount has much thicker drop equalizers than the alco version, with a noticeable taper toward the center axle. they are good for u25c, early u28c, and not much else. possibly used under the e33 and 3\e44 electrics, but i don't have photos available....

Yes, the Century version has a different appearance. Otherwise we'd have all put RSD4/5 trucks under our Stewart Centuries

And the U25C/E33 trucks are trimounts but are very very different from the Alco version, with much heavier drop equalizers than the Alco version.

I think the SP's C643dh's had a third type of Alco tri-mount.

No, the same Tri-Mount, just reversed to accomodate the Carden shafts and Voith hardware.

I just uncovered a mass of detail parts and cannon EN22 motors, and many sets of different trucks. I know some are alco trucks due to the odd spacing. what do you need? This is all stock from E&P Associates from a few years ago. Some of the parts are fans, dynamic brakes, fans, detail parts, antenna, plows, beacons, hoses, ect
