Weigh That Tow

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 packing for an outback trip, hitching up a tandem caravan, or loading a dual-cab ute, Weigh That Tow helps you visualise weight distribution across your setup to stay within manufacturer ratings. ---------------------------------------- KEY CAPABILITIES ---------------------------------------- • WEIGHT & LIMIT GAUGES Instant visual indicators for Gross Vehicle Mass (GVM), Gross Combination Mass (GCM), Aggregate Trailer Mass (ATM), Gross Trailer Mass (GTM), and Tow Ball Weight (TBW). See immediately whether your setup is within specified limits or exceeds rated limits. • AXLE LOAD & LEVERAGE DYNAMICS Understand how weight distributes across front and rear axles. Dynamic leverage physics calculate rear axle loading and front axle unweighting when hitching your trailer, tracking Gross Axle Weight Ratings (GAWR). • TOWBAR & FUEL TANK RATINGS Track your vehicle towbar capacity rating to monitor tow ball download. Model 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 getaway to an extended 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). The app calculates how item placement affects axle balance and tow ball weight. • CONSUMPTION-BASED WEIGHT SHIFTS Model 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 to help avoid under-inflation wear and heat build-up. • PRE-TRIP & SETUP CHECKLISTS Customise and manage departure checklists and camp setup/pack-up procedures with step-by-step verification so nothing is overlooked. • PREVENTATIVE MAINTENANCE LOGS Record service histories, track running gear checks (bearings, brakes, suspension, tyre rotations), and receive automated notification reminders when maintenance is due. • PDF REPORTS Export multi-page weight summaries and verification reports. ---------------------------------------- FREE VS PRO TIERS ---------------------------------------- FREE TIER (Everything needed for a single touring setup): • 1 Active Vehicle Profile • 1 Active Tow Profile • 1 Trip Profile • Up to 20 Inventory Items • Live Calculations & Specified Limit Checks • Departure & Setup Checklists • Ad-supported PRO SUBSCRIPTION (Unlock unlimited touring freedom): • 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 • Consumption Dynamics & Stage Slider • Calculated Operating Tyre Pressures • Maintenance Due Notifications & Service History Tracking • Multi-Page PDF Export Reports with QR Verification • Ad-free experience & multi-device cloud synchronisation
