New to the forum, but felt I needed to reply to this topic. In 2012 I was cited for double towing in Oregon, swivel wheel behind my 30 foot fifth wheel. When I returned home I attempted to get clarification on whether the swivel wheel is a trailer or an extension of the fifth wheel. I contacted the Manager of the Oregon State Motor Carrier Field Services to explain to that the swivel wheel platform was not a trailer because it is permanently attached to the fifth wheel trailer. It is bolted at two points to the fifth wheel frame, pictures were sent to him. He and the manager the Over-Dimension Permit Program got together and looked at the information I submitted and the manufacturers' website. The following was their reply:
We consider the Cruiserlift and other similar devices that have two or more attachment points and do not pivot at the attachment point to be but an accessory to extend the load length of the vehicle it is attached to, not a trailer.
This means that any vehicle that the Cruiserlift or similar devices are attached to is still subject to vehicle length limits. In Oregon that means a recreational vehicle may only be 45 feet long inclusive of the accessory deck added on.
I submitted their findings to the court and the ticket was voided. I will be returning to Oregon this summer.
