====== Rolling River Ranger-M Utility Platform ====== The **Rolling River Ranger-M** is a 6×6 multi-role utility truck developed by the **Rolling River Carriage Company (RRCC)** during the early years of the Industrial War. It was designed to solve a problem no one else was addressing: how to move self-contained field facilities (kitchens, aid stations, workshops, and command posts) rapidly along rough, barely-cut tracks where rail could not go and normal wagons bogged down. Built on an extended, reinforced version of the **Timberwolf** frame, the Ranger-M trades passenger comfort for extreme modularity and off-road performance. It became the backbone “platform truck” for Emberstone’s expedition forces and a quiet workhorse of postwar settlement. ---- ===== Layout and Chassis ===== * **Configuration:** 6×6, high-clearance ladder frame * **Cab:** Single-row steel cab, simple weather hood, seating for driver + 1–2 * **Frame:** Extended flat frame behind cab, factory-drilled for standard RRCC module mounts * **Suspension:** Live beam axles on leaf springs, tuned for heavy loads and rough terrain * **Drive:** Permanent 6×6 with selectable low range; manual locking hubs on all three axles * **Brakes:** Oversized drum brakes, mechanically linked; parking brake on driveline The Ranger-M rolls off the line as a **bare cab-and-frame** unit. Everything aft of the cab is defined by the module bolted to the frame. ---- ===== Powertrain Variants ===== Ranger-M powertrains mirror the early Hydra and bio-electric experiments of the Industrial War. ==== 1. Direct-Drive Hydra Version ==== * **Engine options:** * **Hydra-6 (V6)** – standard fit; ~200 HP class (industry standard) * **Hydra-8 (V8)** – heavy-haul and recovery variants; ~280 HP class * **Transmission:** RRCC heavy 4- or 5-speed manual, shared with Timberwolf * **Driveline:** Transfer case with high/low range and front/middle/rear axle selection * **Use case:** Simple, robust hauler where fuel is plentiful and electrical demand is modest. These trucks behave like over-grown Timberwolves: brutally simple, easy to fix, and beloved by mechanics. ==== 2. Bio-Electric Hybrid Version ==== The hybrid Ranger-M was the first mass-produced “field generator on wheels” in Emberstone. * **Prime movers:** * Twin **Hydra-4 (V4)** or twin **F6** engines, de-rated to RRCC’s conservative tune * **Generator:** * Overbuilt RRCC “Sparkline” traction generator sized for twin engines at **company tune** * Can safely accept brief surges up toward industry standard if both engines are throttled up * **Drive:** * Electric traction motors on all three axles * Mechanical low-gear crawl mode retained for emergency limp-home * **Electrical output:** * Enough surplus to power a full field module (hospital, kitchen, or comms tent) **and** charge portable equipment * External power sockets down both sides of the frame Design logic: * Under normal conditions, both engines idle in their efficient band and feed the generator. * Under sudden heavy demand, drivers “bring up the screws” for short bursts. * If one engine is destroyed (shrapnel, fire, mechanical failure), the other can be over-throttled (within the marked safe band) to keep the truck moving and the module powered—at the cost of higher wear. This “two hearts, one truck” philosophy is why hybrid Ranger-Ms became the preferred platform for frontline medical and command modules. ---- ===== RRCC Tuning Ethos ===== Like all Hydra and F-Series engines, Ranger-M powerplants ship with RRCC’s hallmark adjustable throttle stops: * **Company tune:** Engines are set to a conservative band (~60% of absolute capability) for longevity. * **Industry band:** The adjustment screw is pinned between RRCC and industry-standard marks. Owners may move it freely **within that window** without voiding warranty. * Beyond that, the screw must be physically modified or replaced—clearly outside RRCC liability. On Ranger-M hybrids this matters twice: * Turning both screws up yields more power than the generator was designed to accept and will eventually cook it. * Turning up the *surviving* engine after one is lost restores some lost performance and keeps life-critical modules running. Soldiers quickly learned to treat the screws as a survival tool rather than a toy. ---- ===== Standard Modules ===== Ranger-M modules are standardized steel “boxes” with internal stowage and external fold-out tents or awnings. Most are designed so two to four trained crew can deploy them in under an hour. Common Industrial War modules include: * **Field Kitchen Module** * Fold-out galley tent with stoves, water tanks, prep tables * Powered by truck (hybrid) or auxiliary F-2/F-4 generator * Can feed a full company from a single emplacement * **Barracks / Warm Tent Module** * Fold-out sleeping tent for a platoon-sized element * Integrated heaters or coolers (early heat-pump style units) powered by the truck * Stowage racks for gear and weapons * **Aid Station / Surgical Module** * Sterile interior bay with 2–4 cots and basic surgical equipment * Exterior triage tent that unfolds from the side of the module * Almost always paired with hybrid Rangers for clean, steady power * **Command & Comms Module** * Map tables, radio racks, signal masts, and encrypted long-range sets * Battery banks charged from the truck’s generator or external lines * Often serves as local coordination hub between company and brigade * **Generator Module** * Heavy Hydra-16 or twin Hydra-12 generator for powering trench networks, floodlights, and small railheads * Essentially a rolling power station on a Ranger-M frame * **Biofuel Plant Module** * “Insert biomass here” system: crushes, ferments, and refines plant matter into usable biofuel * Outputs clean-burning fuel plus dried waste bricks that burn like cordwood * Used to keep front-line convoys self-sustaining far from permanent infrastructure * **Recovery / Workshop Module** * Winches, cranes, tool racks, and spares for frontline repairs * Can tow disabled mules, Fox trucks, or even a loaded Timberwolf * **Medevac Module** * Interior optimized for casualty evacuation * Roll-in stretchers, medical lockers, stabilization gear * Paired with hybrid units for climate control and lighting in all conditions * **Pioneer / Community Leadership Module** * Originally fielded as a combined **officer command post** and **pioneer-engineer support unit** during the Industrial War. * Equipped with a compact fold-out **command tent** containing map tables, planning boards, lantern mounts, and a small personal galley. * Hybrid Ranger-M chassis provides continuous electrical output for: * Field radios and signal equipment * Heated drafting surfaces (prevents ink freeze in winter) * Early RRCC power tools for timber work and trench construction * Rear deck forms a reinforced **field desk** when the tailgate is lowered: * Weather-resistant writing surface * Lockable drawers for documents, orders, and survey tools * Integrated shelves and hooks for engineer equipment * The attached **Pioneer Tool Tent** stores: * Pickaxes, saws, shovels, sledges * Rope, braces, canvas, timber-cutting gear * Bio-electric power tools driven off the truck’s generator * Wartime Purpose: * Give officers a mobile headquarters at shifting trench heads * Support pioneer detachments building fortifications under fire * Provide independent power, shelter, and organization * Postwar Role — Rural Emberstone: * Became the de facto **mobile town hall** for early settlements * Used by shire leaders, surveyors, foremen, and community founders * Provided: * The only reliable power source for miles * A drafting and planning center for new homesteads * A tool depot for community construction * A meeting space for disputes and town planning * **In many frontier towns**, the person who owned or operated a Pioneer Module became the natural **community leader**. * The truck itself served as: * Office * Workshop * Power station * Supply depot * Communication post * Cultural Legacy: * Symbol of Emberstone’s pioneer spirit — leadership through labor. * Many shires still keep a restored Pioneer Module in their heritage halls as a reminder of their founding years. All modules share the same mount pattern and power interfaces, allowing commands to swap roles in a depot with minimal tools. ---- ===== Wartime Role ===== During the Industrial War, Ranger-Ms: * Moved with the trench lines as **self-contained support hubs**. * Allowed Emberstone units to establish forward kitchens, aid stations, and command posts **in hours instead of days**. * Created a flexible logistics grid: if artillery found a position, the entire module could be unbolted, craned onto a fresh chassis, and redeployed. They did not lead assaults, but if you followed the Rangers-M you were never far from food, light, tools, or medical care. ---- ===== Postwar Expansion and Civilian Ranger ===== After the war, surplus Ranger-M frames and modules flooded the market: * Estates converted them into **mobile workshops, field clinics, and village power plants**. * Pioneers used them as **rolling homesteads** during the push into Emberstone’s remote regions. * RRCC introduced a more comfortable **civilian Ranger**: same 6×6 bones, but with a full cabin and fixed cargo bed instead of hard military modules. The Ranger-M thus bridged two eras: * On campaign, it was the quiet backbone of Emberstone’s war machine. * In peacetime, it became the vehicle that let ordinary citizens bring civilization with them into the frontier. Even in the Amperion age, many Domains keep at least one Ranger-M or compatible module in reserve—because no matter how advanced the tech becomes, a biofuel truck that can haul its own tent city is never obsolete.
