Axle suggestions?

That's really cool, i don't remember ever seeing a Structo Dozer with a Bellydump! A dozer would probably be easier to work with than upfitting a wheeled tractor power unit.

Hmm, a flat OD green with some black or white stencil could work for like an Army Corps Engineers or Navy Seabee vibe.

I was just kicking around Blast, prime, shoot in white, then keep mixing paint shades to try to do the entire thing in grayscale like a black&white picture. Maybe lettered up as an easter-egg for something obscure like "Shandor Mining Company" or "Kelland Mining Company"...

Looks like in the time period these were made, the "Articulated Dump Truck" was just in infantcy, with Dump trailers hooked to the heavy, slow, torquey, and overbuilt power unit machines that were made to pull a Scraper.
So the Heil or Wooldridge power unit could apply to running both the Belly-dump or a Scraper, but not seeing many pics of a Heil with a belly-dump.

The official Wooldridge bottom-dump attachments i'm commonly seeing has a pretty cool ''box slides off trailer floor'' thing instead of bomb-bay doors of the model. They also had a tip up rear dump available.

Heil - Heiliner 2T55, 2T75
Wooldridge - TerraClipper, TerraCobra TC-Y scraper. CobraWagon, CobraHaul dump

Doepke possibly inspired by the 2H700 / 2H800 models

I hadn't seen that combination before either....it would really help with the traction issue
Black and white...faded paint....letter it in a kind of 50s style.... lots of options if you go that route...

Looks like the Wooldridge tractor is going to work easier than Heil tractor, fair amount more room inside. It should have room for the bigger black-can 12v 90 degree gearmotors.

I need to look into possible motor swaps for the Silver-can gearmotors i ordered to start with. If i can find some, nice 6v rock-crawler cans could probably turn 'meh' power into a beast

Also I found another TournaPull build, starts with a Nylint Tourna-rocker then finding drawings for real one and 3D printing. Also has some narrow gearmotor info and motor swaps

Nice find.... but he had problems finding motors small enough and strong enough to move the truck.... and his had more room then ours will.
