Heavy Transport and Utility Vehicle Concept, Honest Real World Input Wanted

Hey everyone, I’ve been developing a conceptual ultra-heavy logistics truck platform as a long-term engineering thought experiment and wanted feedback from people who actually work around large machinery, heavy haul systems, mining equipment, locomotives, recovery rigs, etc. The core idea is a terrain-independent heavy logistics platform designed around modularity, maintainability, and distributed load management rather than pure speed or flashy technology. The current concept is roughly: Body-on-frame modular chassis using tetrahedral/interlocking truss sections Standardized pinned structural joints where geometry transfers most of the load and the pins mainly act as retention/alignment Rear-mounted transverse 96L short-stroke inline-12 diesel Positive displacement supercharger with efficiency-focused turbocharging Primarily mechanical driveline philosophy with minimal electronics where possible Designed around continuous heavy hauling and operational survivability instead of peak power Integrated maintenance logic (built-in hoist points, extraction paths, removable body sections, service corridors) Airflow/cooling concept uses the unused forward chassis volume as a pressure-fed cooling corridor instead of relying entirely on large dedicated duct systems Modular assembly approach where the machine is assembled in major structural segments before drivetrain/body integration The intended role would be something closer to: ultra-heavy recovery extreme terrain logistics remote megaproject support oversized component transport Arctic/desert infrastructure operations rather than a normal highway truck. One area I’ve been especially interested in is large-scale force management and vibration and fatigue survivability. I’ve been exploring concepts involving distributed structural load paths and controlled flex/compliance instead of trying to make everything completely rigid. I’d honestly love feedback from people with experience around: giant haul trucks locomotives large diesel systems heavy transport driveline harmonics mining equipment structural fabrication field maintenance realities Mainly: what parts sound mechanically reasonable what parts sound completely unrealistic where the biggest engineering nightmares would actually appear and what real-world systems or machines I should study more closely. I’m not trying to pretend this is immediately buildable — I’m more interested in understanding where real engineering constraints would start dominating a machine at this scale. For transparency, I don’t come from a heavy equipment or industrial background professionally. Most of this has come from independent study, observing real machinery design, and trying to understand why large systems are engineered the way they are. That’s a big reason I’m here — I’d rather hear from people with actual operating, fabrication, and maintenance experience than stay trapped in purely theoretical thinking. Appreciate any insight.

Click to expand... seeing the scale of that from the video alone was insane, i can only imagine what it was like in person. i also noticed how much work it took making the local area ready for it i can imagine how much that costs. apart of that is what i was hoping this truck concept would be able to help with without turning absurd for its niche
