No. Every state has different requirements for transporting a trailer through their state. It is impossible for a dealer to be able to comply with the requirements of every state.
If you get stopped by law enforcement, much will depend on what they decide. Some states are very cooperative while others are not.
Be sure to have your MSO (manufacturers statement of origin) and your Bill of Sale with you at all times. Police officers will often not give you a problem if you have these documents but in the end, it is up to them.
Transporters that are DOT licensed and insured have special tags that are in compliance with every state. If you choose to hire someone to deliver your trailer to you, always make sure that they prove they are DOT licensed and insured.
If you the transporter you hire is not licensed and gets stopped by law enforcement, your trailer could be impounded and you may be responsible for all fines and fees.
