RV Tow Check was created for buyers and dealers by an RV owner who experienced the frustrations of RV buying and matching up a tow vehicle with a trailer correctly. This app is a small price to pay considering it is capable of saving one from a very costly mistake.RV Tow Check is the first "Before You Buy an RV" towing capacity calculator that conforms to manufacturers' weight safety and warranty warnings and complies with the SAE J2807 trailer weight rating (TWR) calculation methodology.RV Tow Check answers the most often asked questions, "How much can my truck tow?" or "How much can my SUV tow?" or "How much can my motor coach tow?" RV Tow Check can assist all RV buyers and dealers to ensure tow vehicles are properly matched to any type of towed vehicle.RV Tow Check provides users with the choice of beginner or expert mode of operation. It is recommended that first-time app users start with the beginner mode and learn from the detailed instructions and pertinent details to become an expert user.RV Tow Check simplifies the process of obtaining the realistic vehicle towing capacity for any vehicle towing a trailer, and it is as accurate as the weights that are entered into it.RV Tow Check displays realistic vehicle towing capacity for a fifth wheel or gooseneck, and conventional trailers (bumper pull) simultaneously and provides instant results when selecting various kingpin or tongue weight percentages. RV Tow Check requires a minimum of four inputs by the buyer or dealer. The required entries are gross combination weight rating (GCWR), gross vehicle weight rating (GVWR), the gross vehicle weight (GVW), and trailer weight ratings (TWR) for fifth wheel, gooseneck and conventional trailers. RV Tow Check users have the option to select a fifth wheel hitch if it is not installed in the truck. RV Tow Check users may include any additional unscaled weight for cargo, aftermarket equipment, and passenger weight. The app does not assume everyone weighs 150 pounds as the manufacturers do.RV Tow Check is a must-have tool for anyone owning or considering a tow vehicle less than a late-model one-ton dually truck.
