Yup. 1,800#, as loaded. Regardless of width, length, or axle count.
If you have an Oregon title for the trailer, it was registered and a plate issued for it. Whether that plate was ever mounted is a different story.
If the trailer was not titled, you would have a Certificate of Origin. No title, no registration, and no plate. When you buy a new trailer, you can have the dealer handle the title and registration for you, or you can do it yourself at the DMV. Itās simpler to have the dealer handle it, but you can easily buy your big heavy trailer and tell them you will handle the DMV stuff. The dealer doesnāt care if you actually do it.
Theyāll also often derate a trailer to save on registration fees. Prime example, my 10K pound flatbed is registered as 8K. I didnāt ask for this, and it was 100% the dealerās choice when the paperwork was filled out. Allows me to register it as a light trailer, rather than have a H plate. Shady? Yeah. Iām not concerned for two reasons. Iāve never been stopped by enforcement to check my weight, and Iāve never loaded the trailer past 7,600 gross. I just have more trailer than I need.
