Calculation error
Response from developer
Sorry for the confusion. Nothing has ever swapped in the app, nor is it possible since published. The entry for Hitch GTWR is only for the hitch. The hitch GTWR should be written or imprinted somewhere on the hitch. I think you may be entering the wrong number in the Hitch GTWR entry box. I'm confident the Hitch GTWR is more than 2184 for a fifth wheel trailer hitch. The Hitch GTWR is the published maximum weight rating of the hitch. This information is explained in the app instructions. Example: My Hitch GTWR is 24,000 pounds and the 25% max vertical load is 6,000 pounds.
Impossible to use

You claim that I "wrote about using this app to figure out if a truck and trailer combo is a good fit." Where did you read that? There is no such wording in the description. The second sentence states, "This app simplifies the tasks involved with weighing your tow vehicle and fifth wheel or gooseneck trailer with step-by-step instructions." There's no ambiguity.
Too little too late

DOT inspectors are not responsible for ensuring that a tow vehicle and trailer combination are not exceeding the weight safety ratings. Each vehicle owner is solely responsible and bears all liability. The RV Weight Safety Report is designed specifically for the vehicle owner.
Decent app.
My only complaint is the GTW gross towing rate. I'm not sure what that is. The developer describes it as being stamped on the hitch or located in a decal within the trailer. I could not find such a number or any real description of what it is. As a result, I am not sure about the final numbers for my safety margin vs. overload.
Otherwise a great app. To keep handy on the phone when traveling.

I understand that sometimes it is difficult to find the GTWR. Since there is not a required standard location, each manufacturer may stamp or apply a label at various locations. However, as stated, you could contact the hitch manufacturer, and they should be able to assist you. The gross trailer weight rating (GTWR) is the maximum the hitch is rated to tow.
