As far as having the 12k trailer at a weight of 12k, you will have a percentage of that weight on the rear of the towing vehicle so your aren't really on the edge like you think you would be provided the tow vehicle is rated for it.

Ken, I am not sure if this is what you mean but this is what happened to a farmer friend here in PA. A DOT qualified local from Berks county pulled him in one day while he was delivering hay. He had his 10k trailer hooked up to one of his trucks. While his trailer axle weight was fine hooked up due to the tongue weight on the truck, by itself, the trailer was over.
You see, DOT asked him to drop the trailer so they could weigh it alone. He has a CDL so he was fine there. It cost him around 865 dollars and he had to go change the trailer registration before they would let him move it.
scesnick,
This topic has been covered many times, do a search. Beyond that, I want to make some statements.
Insurance: Most policies only cover light duty applications. Check with your insurer. A lot of companies simply won't insure that heavy trailer.
Manufacturers GVW and GCGVW: Check with your state but usually, the only concern is having your rig adequately registered to cover the wieghts involved. Having an accident is the bigger issue.
Ocasional heavy use is not going to automatically kill your Dodge CTD. I have 200k of often severe duty on mine, having replaced the tranny and the clutch once. The tranny was more due to wanting the modified shaft so I could keep fifth gear and the clutch was more due to the 370 injectors and other goodies that I added.
Finally, while the input from various readers is valuable, the laws in your state in conjunction with the DOT laws have the final say. Though you may not need the licensing that a commercial hauler would, vehicle, securement and safety regs do.
