Why this is so hard to do, is beyond me. This is the third one ive tried and not one actually works properly. ### 5/5 — Good tool *2023-03-20, version 2.03* Wow what a great app! :) ### 1/5 — Kg conversion removed in update 2.0. Update 2.01 did nothing to correct this *2023-03-18* Why provide an update and remove a feature A further update 2.01 did not address removal of feature. What did you fix? A further update yet again and still no inclusion to use kg only lbs. Why? ### 3/5 — Good, but could be better *2022-09-21, version 1.4.0* Not every fifth wheel is going to be a 25% load on the truck. Some provide a worst case king pin weight. It would be great if we could write in our own percent, or a fixed king pin weight. ## Frequently asked questions about GVWR ### What is GVWR used for?
