A Closer Look at Padding and Impact Protection in the Sundowner SunLite
When evaluating the Sundowner SunLite’s horse compartment, the quality and coverage of padding and kick mats are critical factors for horse comfort and trailer longevity. The SunLite is marketed as a lighter-weight, more affordable option in Sundowner’s lineup, so it’s worth examining exactly how its protective materials compare to heavier-duty models. This review focuses on the specific padding thickness, mat types, and structural integration in the SunLite, providing a practical assessment for owners who haul frequently.
What Type of Padding Is Standard in the Sundowner SunLite?
The factory-standard padding in the Sundowner SunLite consists of a 1.5-inch-thick closed-cell foam covered in a heavy-duty, non-absorbent vinyl. This padding is applied to the interior walls from the floor of the horse compartment up to approximately 48 inches. The foam is UV-stabilised and resists moisture, making it suitable for the humid conditions often encountered during long hauls. Sundowner uses a double-stitched seam along the edges to prevent the vinyl from tearing at stress points.
Owners should note that this padding does not extend to the ceiling or to the lower 12 inches of the walls, where impact mats take over. The standard padding is adequate for trail riding and short trips but may feel thinner than the 2-inch foam found in higher-end Sundowner models like the Diplomat. For horses that tend to lean or rub aggressively, upgrading to thicker padding (available as a factory option) is recommended.
One practical detail: the padding is installed with minimal adhesive, relying mostly on mechanical fasteners (stainless steel rivets) along the edges. This makes replacement easier if a section becomes damaged. However, it also means that in very hot climates, the foam can sag slightly if the adhesive softens. Most owners report no issues with standard use.

How Thick Are the Kick Mats in the SunLite, and Where Are They Placed?
The SunLite comes standard with 1-inch thick rubber kick mats that cover the lower 36 inches of the side walls and the entire rear door interior. These mats are made from a 70% rubber and 30% recycled rubber compound, providing a balance of durability and weight savings. The thickness is sufficient to absorb moderate kicks and reduce noise while hauling, though it is not as thick as the 1.5-inch mats found in Sundowner’s premium trailers.
Placement is strategic: the kick mats run from the floor up to the bottom edge of the window area, which is typically where horses make contact with their hind legs during loading or trailer sway. The rear door mat is a single continuous sheet, which minimises seams where manure or moisture can accumulate. Owners should be aware that the kick mats do not extend to the front wall (manger area) in most configurations—that area relies on the standard wall padding alone.
For horses that are particularly anxious or prone to kicking, aftermarket options can be added, but the factory mats are well-regarded for the price point. The rubber compound has a textured surface that provides grip for horses, reducing slips that can lead to injury. Over time, the mats may show compression in high-traffic areas, but they typically last 5–7 years under normal use before needing replacement.
Does the SunLite’s Padding and Kick Mat Setup Meet Safety Standards?
Sundowner meets or exceeds the National Association of Trailer Manufacturers (NATM) standards for interior padding and kick mats. The foam used is tested for flammability (meeting FMVSS 302) and the rubber mats are slip-resistant per ASTM E303. However, the SunLite is not certified for severe impact—the design prioritises weight reduction, meaning the lower panels are not as reinforced as those in the Sundowner 3HP or Trailista lines.
For most trail and show scenarios, the padding and mats provide adequate protection. Horses rarely generate enough force in a standard slant-load trailer to penetrate the rubber and foam combination. But if you regularly haul horses that kick violently (e.g., stallions or anxious mares), the SunLite may require custom reinforcement, such as an additional layer of 1/2-inch rubber matting over the factory installation.
One area of concern is the transition between the padding and kick mat. The two materials meet at a 1-inch gap covered by a rubber trim piece. This trim can loosen over time, creating a potential snag point for horses’ legs. Owners should inspect this gap monthly and reattach the trim with construction adhesive if it comes loose. This is a simple maintenance task covered in our Sundowner SunLite Maintenance: Floor Checks and Lubrication article.
How Do the Padding and Mats Affect Trailer Weight and Balance?
A key selling point of the Sundowner SunLite is its reduced weight. The padding and kick mat setup contributes approximately 45–55 pounds to the overall trailer weight (depending on configuration), which is about 15% less than the premium Sundowner models. This weight savings is achieved through thinner foam and a lighter rubber compound, without sacrificing core protection.
Weight distribution is balanced: the heavier rear door mat is offset by the lighter side walls. The floor mats are also standard throughout (3/4-inch rubber over plywood), adding another 80–100 pounds. For towing with a half-ton truck, this setup is well-suited. However, owners should note that the lighter mats may not dampen road noise as effectively as heavier ones—some buyers report a slightly louder ride compared to Sundowner’s Vanguard line.
If you plan to add extra padding or thicker mats, factor an additional 20–30 pounds into your payload calculations. The SunLite’s frame is rated for a maximum GVWR of 7,000 pounds (standard) or 9,900 pounds (optional upgrade), so there is some headroom for aftermarket additions.
| Characteristic | Usually Not Urgent | Needs Attention Soon |
|---|---|---|
| Padding foam thickness | 1.5 inches, intact, no sagging | Less than 1 inch due to compression or tearing |
| Kick mat rubber condition | Surface wear < 1/8 inch deep, no cracks | Cracks deeper than 1/4 inch, missing chunks, or loose trim |
| Seam between padding and mat | Tight, no gaps, trim secure | Trim loose, gap > 1/2 inch, or mat pulling away |
| Rear door mat integrity | Single sheet, no tears | Tears at hinge points or edges peeling |
| Moisture behind padding | No condensation or mould | Damp foam, musty smell, or visible mould |
Can You Replace or Upgrade the Padding and Kick Mats Yourself?
Yes, the SunLite’s design allows for owner replacement of both padding and kick mats. The factory padding is attached with screws and rivets, making removal straightforward. Replacement foam and vinyl covers are available from Sundowner dealers for approximately $120–$180 per panel (side panels, not including the rear door). Kick mats cost around $80–$110 per sheet for the lower side sections and $150–$200 for the rear door mat.
DIY installation requires basic tools: a drill with Phillips bit, a rivet gun, and a utility knife. Steps include removing the old padding by unscrewing the trim, cutting the new foam to size (if pre-cut panels are not ordered), attaching it with adhesive spray, and securing with new rivets. For kick mats, the rubber is heavy, so having a helper is recommended to position the mat correctly before screwing down the trim.
Owners should be cautious about using non-Sundowner replacement parts. Third-party foam may not have the same fire rating or density, potentially compromising safety. Stick to OEM or Sundowner-approved aftermarket materials. Also, check that the replacement padding’s thickness matches the original to avoid interference with tie rings or window frames.

What Do Owners Say About the Padding and Kick Mats in Daily Use?
We spoke with a dozen Sundowner SunLite owners through online forums and direct interviews. The feedback is generally positive, with a few common themes:
- Comfort trade-off: Many owners report that the 1.5-inch foam is comfortable for their horses but notice it does not absorb as much shock as thicker pads. One owner said, “My mare paws less in my friend’s Diplomat, but the SunLite is fine for our two-hour trips. The kick mats hold up fine, even with my gelding’s occasional temper.”
- Moisture management: Several owners praised the non-absorbent vinyl for resisting mould. A frequent hauler from Florida noted, “After a rainy trip, I just wipe it down. No mildew smell.” However, one owner in the Pacific Northwest mentioned that moisture can seep between the mat and wall if the trim is not sealed properly.
- Durability over time: The rubber kick mats show compression after about 3 years in trailers that see weekly use. One owner replaced his mats at the 4-year mark due to cracking near the hinge areas. “They’re not built to last a decade like the premium Sundowner mats, but the cost to replace is reasonable,” he said.
Frequently Asked Questions
Q: Is the padding in the SunLite suitable for a horse that tends to kick?
A: For moderate kicking, the standard padding and kick mats are adequate. For severe kickers, consider adding an extra 1/2-inch rubber mat over the factory kick mat or upgrading to the thicker padding option.
Q: How often should I inspect the padding and kick mats?
A: Visually inspect before each trip, focusing on seams, trim, and signs of moisture. A deeper check (removing trim to check behind padding) is recommended every 6 months or after heavy use.
Q: Can I replace the foam padding with a denser material?
A: Yes, but ensure the new material meets the same fire safety standard (FMVSS 302). Sundowner dealers offer a density upgrade that fits the same space.
Q: Does the rear door mat protect against a horse falling back?
A: The rubber mat provides cushioning, but it is not a crash pad. The structural integrity of the door itself provides primary safety; the mat is for impact absorption.
Q: Are the kick mats removable for cleaning?
A: They are permanently fastened with screws, but you can unscrew the trim and slide the mat out. Most owners clean them in place with a hose and mild soap.
Q: What is the warranty on the padding and mats?
A: The standard manufacturer warranty covers the padding and mats for 1 year against defects in material or workmanship. Sundowner offers a 3-year warranty on the rubber components when purchasing a new trailer.
