Our 3 Horse Gooseneck Trailer Design is Safer Than a 2+1 Horse Trailer
The 2+1 horse trailer has been gaining popularity in recent years, but falls short of our 3 horse gooseneck trailer. Our trailer has a shorter wheelbase for easier towing along with a much safer stall configuration.

The 2+1 trailer (top) comes with a cramped front box stall. Next, a traditional slant load trailer (middle) has a stationary rear tack which leaves only one narrow escape door. Compare those to the much safer Double D Trailers 3 horse gooseneck trailer slant load (bottom) with two wide openings and moveable SafeTack compartment.
The Double D Trailer 3 horse gooseneck trailer has stalls that are better able to accommodate large show horses. Plus, the trailer can still be configured to create a front ‘box’ stall inside the trailer. Use this convenient area to groom, tack up, or even just let your horse hang out on show day.

Nobody likes broken glass on their back truck windows!
That's why our 3 horse gooseneck enclosed trailer is ideal for towing with an aerodynamic V-shape nose design that eliminates turning issues common with other gooseneck horse trailers. Plus, our light-weight, super-strong Z-Frame design can be hauled by almost any half ton pick-up truck. If you are unsure if your truck and hitch are rated to haul this size trailer, ask our experts. We can help you figure it out.

Our unique slant load configuration makes excellent use of your trailer’s floor space while still allowing each horse room to feel comfortable.
And the SafeTack design makes loading a whole new experience — better and safer!
In comparison, other horse trailers try to squeeze three horses side-by-side in a straight load configuration. Conventional slant load trailer designs have a dangerous stationary tack storage area in the rear corner of the trailer. This hazardous feature not only causes excess stress for nervous loaders, but it forces both horse and handler into a narrow space without room to maneuver.
In contrast, our patented SafeTack design has an enclosed tack compartment that swings out like a second door. This leaves a wide, open trailer ramp for loading and unloading.
The SafeTack compartment also allows you to keep all your tack and grooming supplies separate from your own stuff, which you can store in the front sleeping quarters. There’s no reason your sweaty saddle blanket needs to be stored with your clean show outfit.
You may have heard that slant stalls are "too small" or "you can't get to all horses individually in case of an emergency." Well, that may be true on most designs from other manufactures, but at Double D Trailers, we custom build your trailer to fit any size horse. In fact, you have the option to add footage to only one stall, two stalls or all three stalls depending on what size horses you plan to haul.
In addition, we make it a priority to provide safe loading and unloading options for each horse. Adding a double side ramp solves the dilemma of unloading each horse quickly in an emergency. It allows you to load from the side and haul your horses in a rear facing position if you so choose.
Keep in mind you may want to include your ramp on the "off traffic" or ditch side in case you have to pull off and unload in hurry.
The safety features on this 3 horse gooseneck trailer are second to none. Once inside, your horses will enjoy a light and airy interior with tubular head dividers that combat your horses’ natural claustrophobia.
The total result is a travel that will keep your horse safe, and that will hold up to the miles you put on it.
All our trailers are built-to-order, so you get a one-of-a-kind trailer designed to suit your specific needs.
This means you can pay for the features that you want and leave out those you don’t. Compared to buying another brand from a local dealer, you are going to get much more value for your dollar… and have a trailer that’s a perfect fit for you and your horses.
Designing a trailer with Double D Trailers is easy! After you submit an online customization request, you’ll be put in contact with one of our expert designers. They will help you refine the design until you have a trailer that you’ll love.
