Arriving at a campsite after hours on the road often presents an uneven parking pad where appliances, slide-outs, and interior comfort depend on getting the rig level. Campers searching for an anderson camper leveler want to eliminate the tilts that make sleeping awkward, swing cabinet doors open, and disrupt RV absorption refrigerators. When pulling into a site, owners must decide whether their rig needs wheel elevation to correct side-to-side slope, frame stabilization to stop cabin bounce, or both. Choosing the right equipment requires understanding whether you are lifting trailer tires, supporting drop-down stabilizer arms, or outfitting a tandem-axle setup.

The product lineup from Andersen organizes campsite setup by separating tire elevation from jack stabilization under the banner of andersen hitches rv leveling. Instead of forcing owners to build stepped pyramids out of plastic squares, the brand engineered curved ramps that elevate the trailer continuously as the tow vehicle moves. Alongside these drive-on ramps, the brand produces modular jack blocks that shorten stabilizer extension to minimize sway. Examining an andersen leveler comparison helps clarify how these tools function, making it easy to determine the exact components required for your axle layout, tire diameter, and campsite stabilization routine.

Check price on Amazon 4.6 out of 5 — average from Amazon buyers

Best for: Campers needing stabilizer jack support

Pros

• Four blocks support all trailer corners
• Stackable up to 14 inches height
• Recessed post hole centers jack feet

Cons

• Not designed for tire leveling
• Limited to 2000 lbs jack loads

Best for: Tandem axle travel trailers and fifth wheels

Pros

• Complete kit with rubber mats and bag
• Supports up to 30000 lbs
• Continuous lift from half to 4 inches

Cons

• Requires adequate space between tires
• Redundant for single axle trailers

For dual-axle travel trailers and large fifth wheels, the Andersen Hitches 2-Pack Camper Leveler Blocks system delivers a matched setup to balance both tires on the low side of the trailer. Designated as model 3604-RTBA, this andersen camper leveler 2 pack supports up to 30,000 pounds and accommodates trailer tires up to 32 inches in diameter. The curved wedge design operates as an rv drive on leveler, allowing the driver to pull forward or reverse onto the ramps in one smooth motion. Instead of stacking individual blocks, you place one ramp against each low-side tire and roll onto them until level. Getting the trailer level quickly lets you focus on camp setup, whether that means deploying slides or plugging in a glade plug in for a welcoming interior cabin.

A major asset of this two-pack kit is the pair of included rubber grip mats. On hard surfaces like smooth concrete pads or slick asphalt, hard plastic ramps can slide forward instead of drawing beneath the rolling tire. These rubber mats sit between the leveler base and the ground, creating high-friction contact that keeps each ramp stationary during entry. The listing highlights precision leveling anywhere from 1/2 inch to 4 inches at any increment, finishing the process in under five minutes. For packing up, both ramps and grip mats store neatly inside the supplied heavy-duty duffel bag with double handles.

This two-pack configuration is designed for tandem-axle travel trailers, toy haulers, and fifth wheels that need balanced support across two adjacent tires. Leveling only one wheel on a tandem axle risks overloading the neighboring suspension and torquing the chassis. Made in the USA with a lifetime manufacturer warranty, this kit provides a complete package. For single-axle trailer owners, however, the extra ramp and duffel bag add unnecessary bulk, making the single-pack unit a more practical choice.

ANDERSEN HITCHES

Once tires are level, stabilizing the trailer chassis to prevent annoying movement requires a different approach, which is where the ANDERSEN HITCHES 4-Pack EZ Jack Blocks Leveling System enters the picture. Identified by model ANDE-3621-4 and part number 3621-4, this four-pack provides dedicated support stands for drop-leg corner jacks. Unlike curved tire ramps, these camper leveling blocks serve as stable pedestals that reduce the distance stabilizer arms must travel. Just as securing a rhino sewer hose for rv camper sanitation handles a core exterior task, placing solid blocks under corner jacks ensures a firm, wobble-free foundation inside.

Each block is rated to handle 2,000 pounds in both single and double-stacked arrangements, covering typical travel trailer stabilizer jack loads. When stabilizer jacks extend toward their mechanical limits, they develop lateral flex that allows the camper to rock when occupants walk inside. Placing these blocks under the jacks shortens arm extension and eliminates sway. On uneven campsites where jacks cannot touch the ground, stacking two blocks yields 14 inches of height. A molded 2-1/2-inch recessed post hole centers post-style jacks, preventing steel feet from shifting off the base.

The andersen ez jack blocks are built in the USA and backed by a lifetime warranty. Note that these units are stabilizer jack stands, not tire ramps; they cannot lift wheels or fix side-to-side trailer tilt. They are built for RV owners who already have tire leveling solved and want to remove interior floor bounce and protect stabilizer jack mechanisms.

02 Camper Leveler 3604

Check price on Amazon 4.1 out of 5 — average from Amazon buyers

Best for: Single axle camper and trailer owners

Pros

• Precise lift from half to 4 inches
• 30000 lb capacity for heavy rigs
• Includes leveler and matching chock

Cons

• Listing does not include rubber grip mat
• Lacks storage bag

Campers with single-axle trailers, teardrops, or horse trailers need an effective tire ramp without surplus gear, making the Camper Leveler 3604 a focused selection. Carrying part number 3604-GFB in a red finish, this single-wheel package contains one drive-on leveler and one chock. The listing emphasizes frustration-free leveling that replaces stepped blocks, helping drivers level single-axle travel trailers, motorhomes, and utility trailers in five minutes or less. By driving onto the curved surface, you adjust height continuously from 1/2 inch to 4 inches before locking the chock in place.

The listing states this single unit supports up to 30,000 pounds and works with tires up to 32 inches in diameter. Interestingly, while similar plastic accessories feature polymer construction, the listing for part 3604-GFB lists metal as its material type with manual operation. The continuous curved ramp provides infinite adjustment within its four-inch range, avoiding the harsh drops common with tiered blocks. Once level, the included chock nests against the ramp base, securing the wheel against rollback before unhitching.

Because the andersen leveler 3604 kit includes only one leveler and one chock, it is intended strictly for single-wheel adjustment. Single-axle trailers require elevation only on the low side, making one unit sufficient. On tandem-axle rigs, attempting to use a single ramp leaves the adjacent wheel unsupported, which creates severe load imbalances. For multi-axle setups, this single model steps aside for the two-pack kit.

Matching a Model to Your Setup

• Tandem-axle travel trailers and large fifth wheels: Choose the Andersen Hitches 2-Pack Camper Leveler Blocks because dual-axle trailers require simultaneous leveling on both low-side tires, and the included rubber mats prevent ramp slippage.
• Single-axle teardrops, pop-ups, and horse trailers: Select the Camper Leveler 3604 since single-axle trailers only need one wheel raised to level the frame, making the single leveler and chock combination ideal.
• Campers experiencing interior floor bounce and sway: Add the ANDERSEN HITCHES EZ Jack Blocks to support corner stabilizer jacks, shorten jack extension, and eliminate lateral movement inside the cabin.
• Sites with steep slopes beneath corner jacks: Use the ANDERSEN HITCHES EZ Jack Blocks in their double-stacked 14-inch configuration to bridge deep elevation gaps where standard jacks cannot reach the ground.
• RVers deciding which andersen leveler to buy on a focused setup: Opt for the Camper Leveler 3604 if you tow a single-axle rig and do not require extra rubber grip mats or a storage duffel.

Before You Buy

Before ordering an andersen camper leveler, verify the spacing between your trailer tires if you have a tandem-axle trailer. The product listings do not specify the minimum clearance required between adjacent tires to slide two curved ramps into position. On trailers with closely spaced axles, the tail of the front leveler can contact the front edge of the rear leveler. Some owners find they must trim the thin end of one ramp to fit tight gaps, though the product listings do not specify instructions or recommendations for modifying the ramps.

Additionally, the listings do not provide load-bearing ratings for loose gravel, soft sand, or mud. While the ramps support up to 30,000 pounds on solid ground and the EZ Jack Blocks handle 2,000 pounds each, soft terrain can cause either product to press into the dirt under trailer weight. Note also that the single-pack Camper Leveler 3604 listing does not include rubber grip mats or a duffel bag, so drivers operating on smooth concrete should note that friction mats are absent from that specific listing.

FAQ

How does an rv drive on leveler compare to stepped leveling blocks?

An rv drive on leveler uses a curved ramp that lifts the tire incrementally from 1/2 inch to 4 inches as the trailer moves. Traditional interlocking camper leveling blocks require guessing stack heights, driving onto flat surfaces, and restacking if the height is incorrect. The curved design enables continuous adjustment in a single roll without guessing block tiers.

Can EZ Jack Blocks be used under trailer tires?

No, the ANDERSEN HITCHES EZ Jack Blocks are built specifically as stabilizer stands for drop-leg jacks and tongue jacks, not for vehicle tires. Each block is rated for 2,000 pounds to handle corner stabilizer loads, not the heavier axle weight of an entire RV. Driving tires onto them can damage the blocks and create a safety risk.

Why are rubber grip mats included with the two-pack levelers?

The rubber mats included with the Andersen Hitches 2-Pack Camper Leveler Blocks prevent ramps from sliding on smooth concrete, asphalt, or hard-packed surfaces. As the trailer tire meets the ramp, the rubber mat grips the ground, keeping the leveler stable until the tire rolls upward.

What tire size fits Andersen curved drive-on levelers?

The listings for both the two-pack and single-pack drive-on levelers specify compatibility with tires up to 32 inches in diameter. Tires within this size sit properly on the concave curve for balanced weight support during elevation.

Can EZ Jack Blocks be double-stacked securely?

Yes, the listing confirms that ANDERSEN HITCHES EZ Jack Blocks are rated for 2,000 pounds whether used individually or double-stacked up to 14 inches. Each block features a recessed 2-1/2-inch post hole to keep stabilizer jacks centered securely.
