40 ft hotshot trailer: specs and who needs one

If you ask hotshot owners which trailer they'd buy again, most CDL drivers say a 40 ft gooseneck. The extra deck turns a lot of "can't take it" posts into loads you can call on, and that's worth more over a year than the higher price and extra weight.

Typical specs

Exact sizes for every common hotshot trailer are in hotshot trailer dimensions.

The truck it needs

A loaded 40 ft gooseneck can weigh 25,000 lb or more. With 15% to 25% of that on the hitch, the truck carries several thousand pounds of pin weight. That calls for a one-ton dually at minimum, with a gooseneck towing rating above the trailer's loaded weight and a rear axle rating that handles the pin weight with the truck's own load. Heavy, frequent loads are often better on a 4500 or 5500. See best truck for hotshot.

Payload with a 40 ft trailer

Freight is limited by the trailer's GVWR minus its empty weight, the combined rating, and the truck's own rear axle and GVWR. With a 24,000 lb trailer weighing 8,500 lb empty, the trailer can carry about 15,500 lb, if the truck can handle the pin weight. Run your numbers with the max payload calculator.

CDL impact

Because most 40 ft goosenecks are rated far above 10,000 lb, a 40 ft rig is almost always a Class A combination. That means a CDL, DOT drug and alcohol testing, Clearinghouse registration and usually IFTA and IRP. If you plan to stay non-CDL, a shorter, lighter trailer is the better tool; see non-CDL hotshot trailer.

What 40 ft opens up

• Long steel and pipe: 20 ft lengths with room to secure, and longer bundles.
• Equipment: skid steers, mini excavators and light towers with room for attachments.
• Lumber partials and building materials.
• Two loads at once: two partials headed the same way.
• Vehicles: some 40 ft flatbeds carry two or three cars; dedicated car trailers are covered in hot shot car hauling trailers.

For comparison, a 40 ft deck is far longer than the 26 ft box trucks we also dispatch (see box truck dispatch), and close to the length of semi flatbed partials. That's why 40 ft hotshots compete for many partial flatbed loads.

What it means for pay

More deck and more payload mean more posts you can call on, and better odds of finding a load near your last delivery. Heavier and longer loads also have fewer trucks competing, which supports higher rates. The trade-offs are a higher purchase price, more weight, more fuel and the costs that come with a CDL. Price runs from your own costs with the hotshot rate calculator.

Buying a 40 ft hotshot trailer

1. Pick the rating for your truck and license plan.
2. Choose deck-over or between-the-wheels. Deck-over gives full width; between-the-wheels sits lower.
3. Decide on a dovetail and ramps if you'll haul equipment.
4. Steel or aluminum. Aluminum saves weight and resists rust at a higher price.
5. Check brakes, bearings, lights and the neck on a used trailer.
6. Weigh it before you pay.

Upkeep on a 40 ft trailer

A long trailer under heavy loads wears brakes, bearings and tires faster than a short one. Check brake adjustment and lights before every trip, repack or inspect bearings on the maker's schedule, and keep the deck boards or aluminum floor in good shape so freight and binders sit flat. Replace tires as a set on each axle. Trailer defects are among the most common roadside violations, and a trailer out of service costs every load you can't take.

Driving and parking a 40 ft rig

With a crew cab long-bed truck, a 40 ft gooseneck makes a combination of roughly 60 ft. Plan fuel stops and parking where you can pull through, swing wide on turns and check the trailer in your mirrors on every corner. Some job sites and city streets are tight for this length, so ask about access before you accept a delivery.
