Gross Vehicle Weight Rating, as in how much can you carry, largely depends on the pulling vehicle, but is a combination of truck and trailer ratings, this is what you can haul legally (no cdl 26k regardless, most trucks are not rated for 26k, even if the dealer says they are either way you may still have to pay tonnage), and just because your trailer is rated for 16k, does not mean your truck is rated for 16k, or with truck trailer and load 26k or more...
Gross Vehicle Weight, this is what you weigh, truck trailer, occupants, and load, this cannot exceed your GVWR, or you get fined...
Just be careful out there.
