TowCheck helps you answer the question that matters before every trip: can I safely tow this setup today? Instead of giving you a pile of hard-to-read numbers, TowCheck checks your current vehicle, trailer, and load setup and shows a clear result: Safe, Warning, or Unsafe. Built for SUV, pickup, travel trailer, utility trailer, and boat trailer owners, TowCheck helps you catch common towing problems before you leave, including payload limits, tow rating issues, GVWR problems, and tongue or pin weight concerns. Use TowCheck to: • Run a Quick Check in seconds • Compare estimated and measured values • See what is actually limiting your setup • Understand whether the problem is payload, tow rating, GVWR, or tongue weight • Save vehicle and trailer profiles for repeat use • Compare different setups before a trip • Review practical next-step guidance, not just raw numbers TowCheck is designed for real pre-trip decisions, whether you are loading up for a weekend camping trip, towing a utility trailer for work, or checking if a different hitch or cargo plan changes the outcome. If you tow with a truck or SUV and want a faster, clearer way to check trailer safety before you go, TowCheck gives you a practical answer you can trust. TowCheck provides guidance for planning and reference only. Always confirm final safety decisions with your vehicle door sticker, owner’s manual, manufacturer ratings, and real measured weights when available.
