Every trip starts with the same quiet question: are we under our ratings, and how do we actually know? loadmate answers it with one number. RigScore checks your whole rig, truck, trailer and everything you load, against your weight ratings and shows a 0–100 score with the working shown. Green means your numbers sit inside every rating. Anything less shows you what's over and what moves it, in plain language. Built on the numbers that matter in North America: GVWR, GCWR, GAWR, payload, tongue weight and pin weight, the same terms as your door placard and your scale ticket. WHAT'S IN THE APP Can I Tow It? Free for everyone. Shopping for a travel trailer, fifth wheel or tow vehicle? Enter the specs and see whether the combination works before you sign anything. No account needed. Your rig, profiled once. Truck and trailer specs, dry weights and ratings, hitch position, storage zones. Set it up once and the system runs underneath every screen. Cargo, where it actually rides. Assign gear to storage zones in the trailer and the truck. loadmate works out tongue weight and axle loads from where things sit, not just what they weigh. See the change before you make it. Shift 50 lb from the truck bed to the front compartment and watch tongue weight, axle loads and your RigScore move, before you touch a thing. Weigh-ins that stick. Pull onto a truck-stop scale once, enter the figures, and your baselines update. The score's confidence reflects how current your data is. Tire intelligence. Pressures, age and load margins are watched in the background and raised only when they matter. Maintenance, warranty and trips. Service items, warranty coverage and trip planning stay connected to the same rig profile, so nothing is tracked twice. Exceeding your ratings can complicate warranty claims, loadmate keeps your numbers where you can see them. More than one rig. A travel trailer and a boat, or two tow vehicles, switch setups and everything re-scopes. DESIGNED FOR PEOPLE WHO TOW Plain language, big touch targets, nothing buried two menus deep. If you currently run your weights on a spreadsheet, this will feel like an upgrade, not a learning curve. FREE AND PRO Free: the full Can I Tow It? research tool, plus a complete demo rig so you can explore every feature with realistic numbers. Pro: your own rig, live RigScore, cargo tracking, weigh-ins, simulation, tires, maintenance, warranty and trips. One annual subscription, no tiers. Current pricing is always shown on this page and in the app. Auto-renews unless canceled in your App Store account settings at least 24 hours before the period ends.
