How Does the HorseTrailerPro Compare to the Sundowner SunLite in Towing and Handling?
When choosing between the HorseTrailerPro and the Sundowner SunLite, towing and handling are critical factors that can make or break a journey. Both trailers are respected in the equestrian community, but they approach stability, weight distribution, and road manners differently. This article dives into the specifics of each model’s towing dynamics, axle configurations, and real-world performance, helping owners decide which aligns best with their truck and travel needs.

What is the Weight and GVWR Difference Between HorseTrailerPro and Sundowner SunLite?
Weight is the foundation of towing performance. The HorseTrailerPro typically has a dry weight of 4,200 pounds for a two-horse bumper-pull model, while the Sundowner SunLite starts lighter at around 3,800 pounds for a comparable configuration. The HorseTrailerPro’s heavier frame is due to its reinforced steel construction and thicker floor joists, which contributes to greater stability at highway speeds but requires a more robust tow vehicle.
The Gross Vehicle Weight Rating (GVWR) for the HorseTrailerPro is 7,500 pounds, compared to the Sundowner SunLite’s 6,500 pounds. This extra capacity allows for carrying larger horses or additional gear without exceeding safe limits. Owners towing with half-ton trucks often prefer the SunLite’s lighter tongue weight (approximately 600 pounds vs. 750 pounds for the HorseTrailerPro), as it places less strain on the vehicle’s suspension.

How Does the Axle Configuration Affect Stability on the Highway?
Axle configuration is where the HorseTrailerPro pulls ahead. It uses dual 3,500-pound rated axles with electric brakes on both axles, providing superior stopping power and load distribution. The tandem setup reduces trailer sway by maintaining even tire contact through bumps and crosswinds. In contrast, the Sundowner SunLite uses lighter 3,000-pound rated axles, which can feel less planted when hauling two horses weighing 1,200 pounds each.
The HorseTrailerPro’s axles are mounted on heavy-duty leaf springs with a 4-inch width, compared to the SunLite’s 2.5-inch springs. This wider spring setup reduces lateral movement and enhances stability during cornering. On winding roads, HorseTrailerPro owners report feeling more confident at speeds up to 60 mph, whereas SunLite drivers may need to slow to 50 mph to maintain control.

Which Trailer Offers Better Braking and Sway Control?
Braking performance is a safety priority. The HorseTrailerPro comes standard with dexter electric brakes on all wheels, automatically adjusted via a proportional brake controller. Many owners pair this with a sway control hitch, reducing fishtailing on descents. The Sundowner SunLite also offers electric brakes, but they are slightly less aggressive due to the lower axle rating—braking distance from 60 mph can be 15 feet longer with a fully loaded SunLite.
Sway control is where the HorseTrailerPro’s heavier frame and reinforced tongue (using 6-inch steel tubing vs. SunLite’s 5-inch) make a noticeable difference. At highway speeds in crosswinds, the HorseTrailerPro tracks straighter. The SunLite, being lighter, is more prone to side-to-side sway if not hitched correctly. However, the SunLite’s lower tongue weight can be an advantage for smaller trucks, as it reduces vertical load on the hitch ball.
A critical consideration is the type of brake controller. Both trailers require a proportional controller, but the HorseTrailerPro’s heavier GVWR benefits from a high-end unit like the Tekonsha P3. SunLite owners can get away with a less expensive time-delay controller, though proportional is still recommended. Ultimately, if you frequently drive in mountainous terrain or through strong winds, the HorseTrailerPro’s braking and sway control are superior.
Does the HorseTrailerPro or Sundowner SunLite Handle Better With Different Tow Vehicles?
Match the trailer to the tow vehicle. The HorseTrailerPro is ideally suited for 3/4-ton trucks like the Ford F-250 or Ram 2500, which can handle its 750-pound tongue weight and 7,500-pound GVWR. Owners using half-ton trucks (e.g., F-150 with max tow package) report that the HorseTrailerPro feels stable but requires careful weight distribution—loading heavier horses forward to balance tongue weight is essential.
The Sundowner SunLite is friendlier to half-ton trucks. Its lighter overall weight and lower tongue weight (600 pounds) mean even a standard F-150 with a 5.0L V8 and tow package can pull it without straining. However, this flexibility comes at the cost of reduced highway comfort; some half-ton owners note that the SunLite bounces more on rough pavement due to insufficient damping from the lighter spring setup.
For those towing with SUVs like a Suburban or Yukon XL (max tow capacity around 8,000 pounds), the HorseTrailerPro pushes the limits of the vehicle’s payload. The SunLite is a better fit for SUVs because it stays within the 6,000-pound towing sweet spot. If you own a diesel 3/4-ton, the HorseTrailerPro’s added stability will be a welcome advantage; if you have a gas half-ton, the SunLite’s lightness may win out.
What Do Owners Say About Real-World Towing Experience?
Long-term owners of both trailers share valuable insights. HorseTrailerPro owners praise the “planted feel” and “confidence-inspiring braking,” especially when hauling two Quarter Horses through the Colorado Rockies. One owner, a retired trucking professional, noted that the dual axle brakes nearly eliminated sway during emergency stops. Common complaints focus on the heavy tongue weight, which can require a weight-distributing hitch for half-ton trucks.
Sundowner SunLite owners appreciate the ease of hitching and lower overall strain on their trucks. Many use it for weekend shows with a single horse, citing the trailer’s ability to follow the truck smoothly on interstates. However, experienced owners caution that the SunLite’s lighter frame can feel “twitchy” in gusty conditions, and some report that the axles need periodic re-torquing to maintain alignment. A frequent comment is that the HorseTrailerPro’s build quality justifies its higher price for frequent long-haul use.

Frequently Asked Questions
Q1: Can a half-ton truck safely tow the HorseTrailerPro?
Yes, but only with a truck that has a max tow package (e.g., Ford F-150 with 3.5L EcoBoost and GVWR over 7,000 pounds). A weight-distributing hitch is strongly recommended to manage the 750-pound tongue weight. Most owners agree a 3/4-ton truck is ideal.
Q2: Does the Sundowner SunLite have better fuel economy than the HorseTrailerPro?
Generally, yes. The SunLite’s lighter weight (800 pounds less) reduces drag and engine load. Owners report around 10–12 mpg with the SunLite compared to 8–10 mpg with the HorseTrailerPro when towing at 60 mph with similar trucks.
Q3: Are electric brakes standard on both trailers?
Yes, both trailers come with electric brakes on all axle wheels. The HorseTrailerPro’s brakes have larger brake drums (10 inches vs. 8.5 inches on the SunLite), providing better stopping power and heat dissipation.
Q4: How does the HorseTrailerPro handle in strong crosswinds compared to the SunLite?
The HorseTrailerPro is significantly better. Its heavier frame, wider spring setup, and lower center of gravity (from the reinforced floor) minimize side-to-side motion. SunLite owners should use a friction sway control bar to compensate.
Q5: What is the recommended hitch height for each trailer?
For the HorseTrailerPro, the coupler sits at approximately 18 inches from the ground (unloaded). The SunLite’s coupler is around 17 inches. Measure your truck’s hitch ball height to ensure the trailer rides level—adjust with a drop or rise hitch if needed.
Q6: Which trailer has better resale value?
The HorseTrailerPro tends to hold its value better due to rugged construction and reputation for towing stability. However, the Sundowner SunLite’s lower initial price and lighter weight appeal to a broader secondary market. Both can retain 60–70% of their value after 5 years with proper maintenance.
