GVW on a trailer seems a little difficult to verify if you get pulled over. Wouldn't they have to take portable scale readings with and without the trailer attached to figure the hitch/pin weight to add to the axle weights? I suppose if they were using portable scales, they could detach and read it directly.

[EDIT] As much as I have a general dislike for any government requirements and regulations, I looked over the training material for their "house trailer endorsement" and it might not be a bad idea for it to be required reading for everyone. Saved a copy to my desktop.
