RV Tow Check is the first "Before You Buy 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 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 already 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.
RV Tow Check is a small price to pay considering it’s capable of saving one from a very costly mistake.

Red, yellow, greens misleading
The developer is implying that only 22 to 25 percent 5th wheel hitch weight percentage is safe while 15 percent is complexly unsafe. SAE J2807 uses 15 percent for testing. The safe range is 15 to 25. Below or over that is where warnings should be.
After reading the developer response I stand by my assertion. Most people take the colors of red, yellow, and green as safety indicators with green being safe and red being unsafe.
The implication of the app is that towing at 15% pin weight an unsafe towing situation. If the tow vehicle’s GVWR is not exceeded by the pin weight and additional cargo and the GCWR and/or the mfg tow rating not exceeded 15% pin weight is safe.

No sir, I am not imply anything like that. If you had read the info shown in beginner's mode you would have read this: "The red, yellow and green zones are safety guidelines for when you do not know the loaded trailer's pin weight (PW) or tongue weight (TW) percentages."
Most people have no idea what the real pin weight of a trailer will be before purchase. The app provides max realistic vehicle towing capacity for each percentage selected. Those who wish to ensure their tow vehicle will most likely not be overloaded, they will select a percentage in the green zone and not purchase a trailer with a GVWR greater than the selected percentage on the app.
Furthermore, additional info may be read on the app's FAQ page.
If you understand vehicle weights...it works great!
If you understand vehicle weights this can save you some time. Tongue weight as a percentage of total weight needs to fall in the correct range. To me the cautions at the low tongue weight are easily misunderstood.
The red doesn’t mean they aren’t safe...it means your trailer may or may not be able to achieve a low tongue weight. Some can some can’t. The yellow means it is more likely you can reach that tongue percent but again, not all trailers can. The green just means it should be possible for any proper trailer to reach that tongue weight percent.
Maybe overly simplified but a pretty good warning to people too.
Thanks for the app.

Thank you for your 5-star rating and feedback. I will consider your excellent comments in the next app upgrade. If you ever have any questions, please contact me at https://rvtowcheck.com/contact_us.html.
My wife and I have been looking for a travel trailer for several months and it has been extremely frustrating to figure out how much weight my truck could safely tow. And, we constantly got different answers from RV sales persons. We then found this app and it is the best purchase we made and we are now in the final stages of buying a travel trailer that we know my truck can handle. I did have a few questions understanding the results and Dave was very responsive and helpful. I recommend this app to anyone that is considering a travel trailer or fifth wheel! Thanks Dave!
