Weigh That Tow vs RigID

Take the guesswork out of touring, towing, and payload management with Weigh That Tow, the dedicated rig weight calculation app built for Australian 4WDs, caravans, campers, boat trailers, and trade setups. Whether you are packing for an outback expedition, hitching up a tandem caravan, or loading a dual-cab ute, Weigh That Tow helps you visualise weight distribution across your entire combination to ensure you stay within specified manufacturer ratings. KEY FEATURES WEIGHT & LIMIT GAUGES • Instant visual feedback on Gross Vehicle Mass (GVM), Gross Combination Mass (GCM), Aggregate Trailer Mass (ATM), Gross Trailer Mass (GTM), and Tow Ball Weight (TBW). • Dynamic colour-coded status shows whether your combination is within specified limits or exceeds rated limits. AXLE LOAD & LEVERAGE DYNAMICS • Model weight distribution between vehicle front and rear axles. • Leverage physics to accurately calculate rear axle loading and front axle unweighting when hitching your trailer, tracking Gross Axle Weight Ratings (GAWR). TOWBAR & FUEL TANK RATINGS • Track vehicle towbar capacity ratings to monitor tow ball download against manufacturer specifications. • Configure fuel tank capacity to evaluate weight distribution between empty and fully fuelled states. TRIP PROFILES & SCENARIO PLANNING • Create tailored packing profiles for different trips — from a weekend off-road trip to an extended interstate tour. • Switch setups instantly without recalculating from scratch. SMART INVENTORY & COMPARTMENT PACKING • Catalogue gear with item photos, exact weights, and assigned storage compartments (e.g. front boot, roof rack, rear tub, underbed storage). • Item placement automatically recalculates axle balance and tow ball weight. CONSUMPTION-BASED WEIGHT SHIFTS • Dynamically simulate how consuming water and fuel shifts weight distribution over a journey. • Use the interactive trip slider to view your combination mass at departure, mid-trip, and arrival. CALCULATED OPERATING TYRE PRESSURES • Estimate cold operating tyre pressures based on your actual, calculated axle loads and load bias, helping avoid under-inflation wear and heat build-up. PRE-TRIP & SETUP CHECKLISTS • Customise and manage departure checklists and camp setup/pack-up sequences with step-by-step verification so essential checks are never missed. PREVENTATIVE MAINTENANCE LOGS • Record service history, track running gear inspections (bearings, brakes, suspension, tyre rotations), and receive notification reminders when servicing is due. TAMPER-EVIDENT PDF REPORTS • Generate and export professional multi-page weight summaries and verification reports featuring tamper-evident QR verification. --- FREE VS PRO SUBSCRIPTION FREE TIER: • 1 Active Vehicle Profile • 1 Active Tow Profile • 1 Trip Profile • Up to 20 Inventory Items • Live Calculations & Specified Limit Checks • Departure & Camp Setup Checklists PRO SUBSCRIPTION (Monthly or Annual Auto-Renewing): • Unlimited Vehicle, Tow & Trip Profiles • Unlimited Inventory Items with photo tagging • 1-Tap Starter Gear Presets (4WD, Camping, Caravan packs) • Bulk CSV Inventory Import & Export • GAWR Front & Rear Axle Leverage Physics • Dynamic Consumption Modelling & Stage Slider • Calculated Operating Tyre Pressures • Maintenance Due Notifications & Service History Tracking • Multi-Page PDF Export Reports with QR Verification
