Why We Decided to Test the MaxxHaul 50970 Stabilizer Jacks

Our testing journey began after experiencing frustrating wobbles and instability with our previous stabilizer setup. We needed a solution that could handle uneven terrain, provide genuine stability (not just the illusion of it), and withstand the rigors of frequent setup and teardown. The MaxxHaul 50970 caught our attention with its 1,000-pound capacity per jack and telescoping design, promising the kind of heavy-duty performance we were seeking.

First Impressions: Unboxing and Build Quality

Right out of the box, these stabilizer jacks feel substantial. The set of two arrives well-packaged, and the first thing we noticed was the robust construction. Unlike some flimsy alternatives we’ve encountered, the MaxxHaul jacks feature heavy-gauge steel that immediately inspires confidence. The powder-coated finish looks professional and designed to resist the elements—a crucial consideration for equipment that’s constantly exposed to dirt, moisture, and road grime.

The swing-down mechanism operates smoothly, and the telescoping action extends from 12 to 18 inches, providing excellent versatility for various setup scenarios. We appreciated the attention to detail in the welding and overall craftsmanship; these aren’t cheaply made accessories hastily thrown together.

Key Features That Impressed Us During Real-World Use

Telescoping Design: Adaptability When You Need It Most

The 12-18 inch adjustable range proved invaluable during our testing across different campgrounds. We encountered everything from relatively level concrete pads to sloped grassy areas, and the telescoping feature allowed us to achieve solid contact with the ground in every situation. The adjustment mechanism is straightforward—no complicated threading or frustrating mechanisms that bind up when you’re trying to make quick adjustments in fading daylight.

1,000-Pound Capacity Per Jack: Genuine Stability, Not Marketing Hype

We tested these jacks on our 28-foot travel trailer, which weighs approximately 6,500 pounds loaded. With four stabilizers in total (this set of two for the rear, plus our existing front jacks), the weight distribution was excellent. What impressed us most was how dramatically these jacks reduced interior movement. Walking through the trailer felt noticeably more stable, and that annoying rocking motion when someone shifts position virtually disappeared.

The 1,000-pound capacity isn’t just a number on the packaging—it translates to real-world performance that you can feel the moment you step inside your stabilized RV.

Swing-Down Mechanism: Faster Setup, Less Frustration

Anyone who’s wrestled with bolt-on stabilizers knows the aggravation of aligning holes and threading bolts while crouching under a trailer. The swing-down design eliminates this headache entirely. During our testing, we timed our setup, and we could deploy both jacks in under three minutes—a significant improvement over our previous 10-15 minute struggle with traditional designs.

The pivot points are well-engineered and operate smoothly even after months of use. We intentionally left these jacks exposed to rain, dust, and temperature fluctuations to test their durability, and they’ve shown no signs of seizing or difficulty in operation.

Installation Process: Our Step-by-Step Experience

We installed these jacks on our trailer’s rear frame, and the process was refreshingly straightforward. The mounting brackets are pre-welded to the jacks, which simplifies installation considerably. Here’s what our installation looked like:

What You’ll Need: A drill, appropriate drill bits, mounting bolts (check your specific trailer requirements), a wrench set, and about 45 minutes of time.

We positioned the jacks at the rear corners of our trailer frame, ensuring they were mounted to solid structural members—never to decorative trim or non-load-bearing components. The mounting holes aligned perfectly, and we used grade 8 bolts for maximum security. One tip we learned: apply a thread-locking compound to prevent vibration from loosening the bolts over time.

The swing-down action cleared our trailer’s underbelly components without interference, though we recommend measuring your specific clearances before purchasing to ensure compatibility with your rig’s configuration.

Performance Across Different Terrains and Conditions

Gravel and Dirt Sites

On softer surfaces, we used jack pads (2×6 wood blocks work great) to prevent sinking. The wide footplate on the MaxxHaul jacks distributes weight effectively, and we experienced no issues with the jacks punching through or becoming unstable. The telescoping feature allowed us to account for uneven ground, and we could fine-tune the height until our trailer was perfectly level.

Concrete Pads

On hard surfaces, these jacks truly shine. The solid contact point eliminates that floating feeling some stabilizers create. We noticed significantly less vibration transmission from outside foot traffic and wind movement.

Sloped Sites

This is where the 6-inch adjustment range proved most valuable. We camped on a site with a noticeable slope, and the ability to extend one jack significantly more than the other allowed us to achieve stability we couldn’t have managed with fixed-length stabilizers.

What Makes These Stabilizers Stand Out from the Competition

Having tested various stabilizer jacks over the years, several aspects of the MaxxHaul 50970 set them apart:

The Weight-to-Strength Ratio: These jacks are substantial enough to inspire confidence but not so heavy that they’re cumbersome to operate. We’ve used heavier duty jacks that were overkill for our application and lighter jacks that felt flimsy—the MaxxHaul hits the sweet spot.

Corrosion Resistance: After exposure to coastal salt air, road salt, and general moisture, the powder coating has held up remarkably well. We’ve seen minimal surface rust, and what little oxidation appeared was superficial and easily addressed with a wire brush.

Value Proposition: Compared to premium stabilizer systems costing two to three times as much, the MaxxHaul delivers comparable performance at a fraction of the price. This isn’t the cheapest option available, but it’s positioned perfectly in the sweet spot of quality and affordability.

Long-Term Durability: What We Observed After Extended Use

Over six months and approximately 20 camping trips, these stabilizers have proven their durability. The pivot points still operate smoothly, the telescoping mechanism hasn’t developed any play or wobble, and the mounting points have remained solid with no signs of stress or cracking.

We did perform basic maintenance: occasional application of spray lubricant to the pivot points and periodic tightening of the mounting bolts (they settled slightly after the first few uses, which is normal for any trailer hardware). This minimal maintenance requirement is a significant plus for those of us who prefer spending time camping rather than wrenching.
