Reading the requirements from NY law, which I trust is consistent with CDL requirements, the GVWR of the trailer is not part of the formula if it is 10,000 lbs or less. If it is true that the gross GCWR can be calculated by adding the GVWR of the truck to the GVWR of the trailer then, if your truck weighs less than 26,001 lbs, you can still tow a trailer if the trailer's GVWR is less than !0,001 lbs without a CDL even though the GCWR is as much as 36,000 lbs. This is how I read the law, but I would be interested in hearing from anyone who has experience that differs.
