I once bought a horse trailer that looked good in photos.

The price was low. The dealer talked fast. And I was in a rush. So, I bought it.

But a month in? The rear gate jammed. The floorboards felt soft. And customer service? Gone.

That trailer sat in a lot more than it hit the road. I felt stuck.

Since then, I’ve learned how to spot the warning signs. I’ve compared models, talked to dealers across Oklahoma, and helped others make smarter decisions.

If you’re shopping for a horse trailer, this article will help you avoid the mistakes I made. You’ll see 4 trusted horse trailer manufacturers in Oklahoma.

I’ll break down their product quality, pricing, reliability, and after-sales support so you can figure out which one fits your needs. By the end, you’ll have the right questions to ask, and the tools to make the best choice for your needs.

So let’s dive in!

1. Quick Comparison Chart

Before we dig into each manufacturer in detail, here’s a quick side-by-side look. This table gives you a snapshot of what each brand offers, so you can spot the differences.

2. Sundowner Trailers

Sundowner Trailers started back in 1976 in Coleman, Oklahoma. A small-town shop with big ideas. It was founded by the Shipman family, who saw a gap in the market for lighter, longer-lasting horse trailers.

They were one of the first to focus on all-aluminum construction. No steel meant no rust. That simple shift helped them grow fast.

Today, Sundowner sits on 190 acres of land. Their facility covers over 500,000 square feet. They’ve grown from a family-run operation to one of the biggest horse trailer builders in the country. And they’re still based in Coleman.

If you’ve been around horse trailers for a while, you’ve probably seen a Sundowner.

Products and Services

Sundowner builds a wide range of trailers, including:

• Horse trailers (slant-load, straight-load, living quarters)
• Livestock trailers
• Cargo and utility trailers
• Toy haulers and car haulers

All of them use aluminum for durability and lighter weight.

You’ll find both standard models and some room for customization. Dealers work with the factory to help you choose interior layouts, tack storage, windows, and more.

They also offer:

• An online parts store
• Warranty support
• Dealer service centers across the U.S.

Manufacturing and Facilities

Everything is built in Coleman, OK.

They don’t outsource. Frames, welding, wiring—it’s all done on-site. That helps them keep control over every step.

Their campus includes:

• Over 545,000 square feet of production space
• Assembly lines for different trailer types
• Welding stations, paint booths, and QC areas
• A team of 200+ workers

It’s a big operation. But still grounded in Oklahoma values.

Quality, Certifications, and Support

Sundowner is a member of the National Association of Trailer Manufacturers (NATM). That means their trailers meet safety rules set by the U.S. Department of Transportation (DOT).

Every trailer goes through multiple inspections—welds, wiring, doors, and lights are all checked.

Their warranty is competitive, and most dealers help with parts and repairs. I’ve had friends call Sundowner directly and get help fast. That says something.

Final Thoughts

Sundowner makes strong, all-aluminum trailers. You’ll get good value, solid dealer support, and a long-lasting product.

If you need a basic two-horse trailer or a big hauler with living space, they’ve got options.

Downside? Fully custom orders have limits. And prices can run high on larger models.

But if you’re looking for a trailer that holds up—and a name you can count on—Sundowner is a solid place to start.

3. Sooner Trailers

Sooner Trailers has been around since 1956, starting out in Duncan, Oklahoma. What began as a small operation focused on stock trailers grew into something much bigger over time.

They’ve seen decades of changes in the trailer industry but kept one thing steady: building strong trailers that hold up over the long haul. Today, Sooner is part of the Universal Trailer Corporation, alongside Exiss. Even with that growth, their production still happens right here in Oklahoma.

If you’re looking for a brand with history—and one that’s still active in the local community—Sooner checks that box.

Products and Services

Sooner makes trailers for serious work and travel. Their lineup includes:

• Horse trailers (slant-load, straight-load, and models with living quarters)
• Stock trailers for cattle, goats, and other livestock
• Combo trailers, which blend horse and cargo space
• A few cargo and utility trailers

They use aluminum construction, which helps cut down weight and reduce rust. That makes a difference if you’re towing long distances.

You’ll find:

• A wide range of floor plans
• Tack room options
• Living quarters from third-party installers
• Dealer support and service
• Help with financing through partners

Manufacturing and Facilities

Sooner builds all their trailers at a shared plant with Exiss in El Reno, Oklahoma.

This facility handles:

• Welding and assembly
• Interior build-outs
• Electrical and brake testing
• Final checks before delivery

It’s a modern setup with a focused team, and they’ve kept production local, which helps keep standards consistent.

Quality, Certifications, and Support

Sooner is NATM certified, meaning their trailers follow strict safety standards set by the National Association of Trailer Manufacturers and DOT.

Each trailer goes through:

• Structural checks
• Electrical testing
• Brake and axle inspection
• A final inspection before it leaves the factory

They offer a solid 8-year limited structural warranty. If something goes wrong, you’ll likely be working through one of their dealers. Most owners say support is dependable—though it can vary by location.

Final Thoughts

Sooner is a good fit if you want a trailer built to last. Their designs are clean. The welds are strong. And you can tell the factory team takes pride in their work.

Downsides? They’re not the cheapest. And getting custom features might take longer since they work through dealers.

Still, if you’re hauling valuable horses or livestock and need a trailer, you can rely on—Sooner is a name worth keeping on your list.

4. Jackson Trailer Manufacturing

Jackson Trailer Manufacturing was founded in 1980 and is located in Cyril, Oklahoma. It started as a small, family-run shop focused on ranch and utility trailers. Over time, it grew into a trusted regional builder with a solid reputation in the agriculture and livestock space.

What stands out about Jackson is their commitment to building no-nonsense, dependable trailers for working people. They’re not flashy, but they do the job—and that’s exactly what some buyers are looking for.

You won’t find national ads or a huge sales team. This is an Oklahoma-grown operation that still keeps things local.

Products and Services

Jackson builds several trailer types, including:

• Horse trailers (primarily straight-load and slant-load options)
• Stock trailers
• Flatbed utility trailers
• Gooseneck trailers

Most of their buildings use steel frames and floors, which add strength but can also mean more weight. For buyers who prefer steel over aluminum, Jackson is a go-to.

They also offer:

• Custom sizing and floorplans
• Tack room additions
• Spare parts and replacement services
• Paint options (usually powder-coated for durability)

Sales are handled directly through their office or approved dealers across the state.

Manufacturing and Facilities

All trailers are built in-house at their Cyril facility. While the shop isn’t massive, it’s well-equipped for mid-volume production.

The facility includes:

• Welding bays
• Fabrication equipment
• Paint and finishing stations
• A small crew with years of experience

You won’t find robotic welders or giant assembly lines. But you will find skilled hands and trailers built one at a time.

Quality, Certifications, and Support

Jackson follows DOT safety standards and includes lighting, brakes, and axles that meet federal guidelines.

They are a member of the NATM, which helps maintain build consistency and safety checks.

Each trailer is inspected before delivery, though the process is more manual than automated.

Support is mostly done through direct contact. If you call, you’ll likely speak with someone who’s been there for years. That kind of continuity matters.

Final Thoughts

Jackson is a solid pick for buyers who want a tough trailer without the frills. It’s not high-end, but it is dependable. Steel construction means it’s heavier but rugged—something you may want if you’re working around rough roads or pastures.

Downsides? Limited living quarters and fewer modern add-ons.

But if you value simplicity, strength, and an Oklahoma-built trailer that gets the job done, Jackson is worth a closer look.

5. WW Trailer

WW Trailer was founded in 1960 and is based in Madill, Oklahoma. That’s over 60 years of trailer-building experience in one place.

Started by the Wallace family, WW was built on a simple promise: make trailers that work hard and last. Over the years, the company stayed true to that mindset. No frills. No shortcuts. Just honest builds for ranchers, farmers, and horse owners.

They’ve grown steadily and now serve customers across the U.S. but they’ve kept their roots in small-town Oklahoma.

Products and Services

WW makes a range of practical trailers, including:

• Horse trailers (slant-load and straight-load)
• Stock trailers
• Combo trailers
• Utility and cargo trailers

They are built with steel frames and steel bodies. That means added weight but also added strength. These trailers are known for taking a beating and still holding together.

You’ll find:

• Powder-coated paint finishes
• Treated wood floors
• Rubber mats and dividers (on horse models)
• Tack rooms on select models

WW sells through dealers, mostly across the Midwest and South. Some customization is available through dealer requests.

Manufacturing and Facilities

WW’s trailers are built right at their facility in Madill.

The factory includes:

• Welding stations
• Paint booths
• Fabrication areas
• Testing and inspection zones

The operation isn’t flashy, but it’s efficient. Most of the crew has years, sometimes decades of experience. They build in smaller batches, so each trailer gets attention before it rolls out.

Quality, Certifications, and Support

WW is NATM-certified and follows DOT guidelines for lighting, brakes, and safety. Every trailer gets a full inspection before it leaves the factory.

The company offers a 1-year limited warranty. Most issues are handled through your local dealer. Support is simple—if something breaks, they’ll try to make it right.

Final Thoughts

WW Trailer builds tough, no-nonsense trailers for buyers who just need something that works. These aren’t high-tech or fancy. But they’re dependable. And they hold up in rough conditions.

If you haul livestock, run a ranch, or just need a trailer that can take years of abuse—WW is a name worth checking out.

One thing to note: steel means rust if not maintained. And customization is basic.

But if you want something solid, affordable, and made right here in Oklahoma, WW is a strong pick.
