So to the root of these last 4 posts; this utility is very simply based on the math and nothing more. It's a tool where a member of the towing community can hit the CAT scale, plug in their raw data against the corresponding manufacture specifications, and walk away with an understanding of where they fall in comparison. There is no 20% safety margin or subject of towing best practices involved in this tool. That responsibility falls to the user based on their level of comfort. For example this tool will tell you if you're at 99% of your GVWR, but does that mean it's a good idea to be at the bleeding edge of your vehicle limits? That's a question only the user can answer based on their comfort level....
