NMFC 189540 - Trailer Cars, Carts or Coaches | Class N/A

Note 189542: NOTE-Articles may be equipped with household paraphernalia consisting of bedding, furniture and kitchen equipment.

To find the correct freight class for your shipment:

1. Reference Note item 189542 when quoting and specify whether the unit is passenger, house, or sleeper configuration; note any built‑in fixtures or slide‑outs.
2. Measure overall length including the tongue, rooftop A/C or vents, and bumper‑to‑bumper height; provide track width to help select flatbed, step‑deck, or RGN equipment.
3. Prep for transport: empty water tanks, remove propane cylinders, disconnect 12V batteries, secure doors/cabinets/windows, and pad glass and trim; tag approved tie‑down points.
4. Confirm load condition: rolling with working brakes or winch‑required; request soft straps and wheel nets (not chains on exposed axles), wheel chocks, and no‑forklift handling.

Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.

• Correctly citing NMFC 189540 and its note reduces reclass disputes and prevents unexpected accessorials on non‑self‑propelled passenger trailers.
• Non‑hazardous status broadens carrier options and supports standard handling, often improving rates and scheduling flexibility.
• Professional prep (securing interiors, draining tanks) lowers damage risk and claim costs for RV dealers, event fleets, and film production sleeper units.
• Right‑sized equipment (flatbed vs step‑deck) avoids oversize surprises, streamlines loading, and can shorten transit time for time‑sensitive moves.
