Buying a used trailer on Marketplace, starting with the title

A used trailer is a title, a VIN plate and a frame, in that order, because trailers are stolen more than almost anything with wheels and because in most states you cannot register one without paper. The good news is that a trailer is easy to inspect: everything that matters is visible from underneath with a flashlight. Here is the paperwork, the inspection, the homemade-trailer trap, the scams, how to judge the price, and how to be first.

The paperwork, first

• Title. Most states title trailers, some only above a weight, a few not at all. Know your state before you look. Ask for a photo of the title; the VIN on it must match the plate on the trailer. "Lost title" and "bill of sale only" on a trailer that should be titled is a bonded-title project that can take months.
• VIN plate. Riveted to the tongue or the frame near the front. Missing, painted over, ground, or re-riveted means walk. Run the VIN through the free NICB VINCheck before you go.
• Homemade trailers. Legal in most states, but they need a state-assigned VIN and inspection to title, and the welds are whoever's welds they were. If it has no VIN at all, find out what your state requires before you pay a dollar.
• Weight rating. The VIN plate lists the GVWR. Make sure it is rated for what you will haul and what your vehicle can tow.

Underneath, with a flashlight

1. Frame. Rust scale, soft spots you can push a screwdriver into, cracks at the welds where the tongue meets the frame and where the axle mounts, and sagging in the middle. Surface rust is fine. Rot and cracks are not.
2. Axle and springs. Bent axle (the tires wear on one edge), broken or sagging leaf springs, rusted-through spring hangers, U-bolts loose.
3. Bearings. Jack each wheel, spin it, and listen; grab it at 12 and 6 and rock it for play. Pull a dust cap if the seller lets you: dry or rusty grease means bearings soon. Ask when they were last packed.
4. Tires. Trailer tires age out before they wear out. Read the four-digit date code on the sidewall; over five or six years is due regardless of tread. Check for dry rot and uneven wear.
5. Brakes, if it has them. Electric brakes should grab when you touch the controller; check the breakaway switch and battery.
6. Lights and wiring. Plug it in and run through running lights, brake lights, turn signals. Chafed or spliced wiring is a weekend you did not plan.
7. Coupler, jack, chains. The coupler latches and locks on the ball size it says; the tongue jack cranks; the safety chains are present and not stretched.
8. Deck and sides. Rotten boards, a bent ramp, a gate that does not latch, loose stake pockets. Cosmetic unless the crossmembers under the deck are rotten too.
9. Enclosed trailers. Roof seams and corners for leaks, floor for soft spots, door seals, a frame rail under the floor that is not rotten.

The scams

• The deposit to hold it. No.
• Stolen trailers. The most common used-trailer problem there is. VIN plate present and matching, VIN run, seller who can say where they bought it. A trailer priced far below the others with a "friend is selling it" story is somebody else's trailer.
• The homemade trailer sold as titled. Ask to see the title before you drive.
• The out-of-state "shipped" trailer. No.

Meet in daylight, bring a friend, and for a trailer-sized sum do the money and the title at the bank together.

Is the price good?

Trailer prices depend on the type (utility, car hauler, enclosed, dump, equipment), the length and rating, the axle count, the brand, the age, the tires, and the area; a car hauler is priced differently in a farm county and a city. The honest comparison is with the last several like it near you. Deal Scanner does this for you: once a search has seen a few listings, each new one gets a Deal Score showing how far under the typical asking price near you it sits. A trailer far below typical is a motivated seller, a title problem, or a stolen trailer, and the plate and the paperwork tell you which.

Getting there first

Set one search in Deal Scanner for the trailer you want ("car hauler", "enclosed trailer", "6x12 utility trailer", "dump trailer"), your town and how far you will drive, and a price range with a real low limit. Deal Scanner watches Facebook Marketplace, OfferUp and Craigslist from that one search, with the app closed, and buzzes you when a listing is posted, Deal Score attached. Three searches are $3.99 a month, and you cancel anytime in your phone's subscription settings. Only need it for the month you're looking? Cancel when you've got it. It works for the person who needs one trailer for the mower and for the person who buys and sells equipment.

Searches that work: the type plus the size ("7x16 enclosed"), and the brand if you have one ("PJ", "Big Tex", "Load Trail").

FAQ

Does a used trailer need a title?

In most states, yes, sometimes only above a weight. Check your state, and make the VIN on the title match the plate on the trailer. A trailer without a title can be a long project to register.

How do I check if a used trailer is stolen?

Run the VIN through the free NICB VINCheck, make sure the VIN plate is present and untouched, and be wary of a price well under the others with a seller who cannot say where it came from.

What should I check on a used trailer?

The frame for rust and cracks at the welds, the axle and springs, bearing play, tire date codes, brakes and the breakaway, lights and wiring, the coupler and chains, and the deck.

Can I buy a homemade trailer?

Yes, in most states, but it needs a state-assigned VIN and inspection to title and register. Find out what your state requires before you pay.

How do I get alerts for trailers near me?

Set a Deal Scanner search for the type and size, your town, a radius and a price range. It watches Facebook Marketplace, OfferUp and Craigslist and buzzes your phone when a match is posted.
