What Do You Need to Bring When Renting a Trailer?

What do you actually need to bring to pick up a rental trailer? Four things: the right hitch hardware, a working plug, your tie-downs, and proof of insurance. Everything else is optional.

Here is the full list, and why each item matters.

The hitch hardware

A receiver that fits and is rated for the load. The class and weight rating are stamped on the receiver itself. A Class III receiver does not handle a Class IV load.

A ball in the correct size. This is the one people get wrong most often. Most equipment trailers use 2-5/16". Smaller utility trailers usually use 2". They are not interchangeable, and a 2" ball under a 2-5/16" coupler can latch and still come off on the road.

Ask us which size you need before you leave home.

A ball mount with the right drop or rise. You want the trailer sitting roughly level once hooked up. Measure from the ground to the bottom of the coupler, then from the ground to the top of your receiver opening. The difference is the drop you need.

A hitch pin and clip. Easy to forget, and you are not going anywhere without one.

The electrical connection

The right plug. A 4-pin flat carries lights only. A 7-pin round carries lights plus power for electric brakes and the breakaway battery.

If the trailer has brakes, you need the 7-pin. There is no workaround.

A working brake controller, if the trailer has electric brakes. Alabama requires brakes on trailers at or above 3,000 lbs gross weight, and gross weight means the trailer plus your load.

Many trucks with a factory tow package already have a controller built in. Look for a small dial or button near the steering column, or check the touchscreen menus. Our post on brake controllers covers how to tell.

An adapter, if needed. If your truck has a 7-pin and the trailer needs a 4-pin, an adapter handles it. The other direction does not work, since a 4-pin has no brake wire to adapt from.

Tie-downs

Bring your own unless we have confirmed otherwise.

Ratchet straps for smooth or painted loads: mowers, ATVs, UTVs, furniture, boxed cargo.

Chains and binders for heavy equipment with rough edges: tractors, skid steers, steel-framed machines.

Bring at least four. Two straps hold a load down; four hold it in place.

Check the working load limit tag on each one. Your total WLL should be at least half the weight of what you are hauling. A 4,000 lb machine needs tie-downs totaling at least 2,000 lbs of WLL.

Corner protectors if you are strapping over anything with a sharp edge. A folded rag or piece of carpet works.

Paperwork

Your driver’s license.

Proof of insurance. Your auto policy is typically what covers a trailer you tow. Confirm that with your provider before pickup rather than assuming. Some policies cover it automatically, some require you to add it, and some exclude it.

Do this a few days ahead, not in the parking lot.

Useful extras

Not required, but they save trips:

Wheel chocks. For loading and unloading safely.

Work gloves. Chains and couplers are hard on hands.

A tire pressure gauge. Trailer tires run high, often 50 to 65 psi. Checking them cold before you leave is worth doing.

A flashlight. For checking under the trailer and reading stamped ratings on hardware.

A tarp and bungees, if you are hauling anything loose. Yard debris and cardboard become airborne easily.

A basic wrench for checking lug nuts.

Information to bring in your head

The most useful thing is not an object.

Know what you are hauling and roughly what it weighs. Know your truck’s year, make, model, cab and bed configuration, and drivetrain. Know your ball size and plug type.

With that, we can confirm your setup in a couple of minutes and catch a mismatch before it becomes your problem on the road.

How pickup works with us

Our rentals are built to be simple. You book online, sign and pay, and get an access code by text. The trailer is staged and ready when you arrive. You hook up, haul, and return it.

You can read the full process on our how it works page.

If hooking up yourself is not practical, we deliver within 50 miles.

The two things that derail a pickup

In order of frequency:

Wrong ball size. Check the coupler stamp before you leave home.

No brake controller or wrong plug. A 4-pin plug on a trailer that needs brakes stops the rental before it starts.

Both are five-minute checks at home and an hour of frustration at pickup. Take the five minutes.
