Your trailer arrives with a Manufacturer’s Certificate of Origin (MCO) — the birth certificate of the trailer. What happens next depends on your state, but the sequence is the same everywhere: title (if your state titles trailers), register, plate, and decide on insurance. Here is the whole path.

Step 1: The MCO — do not lose it

The MCO (sometimes MSO, Manufacturer’s Statement of Origin) proves the trailer’s origin and first ownership. Your state’s DMV takes it in exchange for a title or registration. Treat it like a car title: it is the document, and replacing one takes time. We deliver it with the trailer — put it somewhere that is not the trailer.

Step 2: Does your state title trailers?

This is the question that splits states. Some title every trailer, some only above a weight threshold, and a few do not title utility trailers at all — registration only. The threshold matters: many states draw the line at 3,000 lb GVWR, which puts our single-axle models (2,990 lb GVWR) under it and our tandem-axle models (7,000 lb GVWR) over it. Check your state’s DMV page before the trip.

Common state patterns (verify with your DMV — rules change)
PatternWhat it means for you
Titles all trailersMCO → title → registration. One extra document, one extra fee.
Titles above a GVWR thresholdSingle-axle models often skip the title; tandems usually need one.
Registration onlyMCO goes straight to registration; keep your bill of sale forever.

Step 3: Register and plate

  1. Bring the MCO, bill of sale, and your ID to the DMV (some states allow online or mail registration for trailers).
  2. Expect a registration fee scaled to weight and any applicable sales tax. Rugged does not collect or handle tax, title, registration, or related fees.
  3. Most states plate the trailer; mount the plate at the rear where the light kit illuminates it.
  4. Renewal cycles vary — some states offer multi-year or permanent trailer registration, which is worth taking if offered.

Step 4: Insurance — the honest advice

Your tow vehicle’s liability policy typically extends to a trailer you are towing — liability, not damage. Physical damage to the trailer itself (theft, collision, a tree in a storm) is only covered if you add the trailer to a policy. On a premium aluminum trailer, that coverage is usually cheap relative to replacement cost. Questions to ask your agent: does my auto policy extend liability while towing; is the trailer itself covered for theft and damage; is cargo covered; and does my homeowner’s policy cover it while parked at home?

Do utility trailers have titles?
Depends on the state and often the trailer’s GVWR. Many states title trailers only above a weight threshold (commonly 3,000 lb GVWR). Your trailer’s GVWR is on its VIN plate — compare it to your state’s threshold.
What if I move to another state?
You re-register (and title, if the new state requires it) with your existing registration and the bill of sale or title. This is another reason to keep every document from delivery day.
Does the trailer have a VIN?
Yes — every Rugged trailer carries a 17-character VIN on a plate riveted to the frame, usually on the tongue. The DMV will want it; insurance will too.
