OULEME Trailer Jack Block for RV Camper Travel Trailer - Stable

In this review the OULEME Trailer Jack Block is judged as a practical, no-frills support block for RV owners who need a stable base for tongue jacks, scissor stabilizers, and jack wheels. The single biggest reason to buy is its combination of compatibility and strength: made from dense PP material with a grooved top for stacking, each block claims up to 15,000 lbs capacity and fits both square and round jack feet as well as 2' tongue posts and 6x2' wheels. For anyone who regularly levels or stabilizes trailers, this feels like a dependable, lightweight addition to a toolkit.

Key Features

• Versatile fit: Works with square jack feet, round jack feet up to 9' diameter, 2' tongue jack posts and typical 6x2' jack wheels so it covers most trailer setups.
• Stackable height: Single block height is 3.9' and two stacked give 9.6' height, making it easy to gain extra lift without tools.
• High load capacity: Each block is rated to support up to 15,000 pounds, providing confidence when stabilizing heavy campers or enclosed trailers.
• Durable construction: Molded from PP with increased density and thickness to resist deformation and handle repeated use in outdoor conditions.
• Improved stacking stability: The top features a groove design that helps prevent slipping when blocks are stacked under a jack foot or wheel.

Who It's For

The OULEME block is best for RV and trailer owners who need a reliable, lightweight support solution for leveling and stabilizing. It suits users with tongue jacks, scissor stabilizers, or jack wheels who want a block that fits multiple foot shapes and provides a secure stacking option.

It is less suitable for someone requiring a large platform for very wide stabilizer feet or a permanent heavy-duty pad for continuous full-time parking; those users should consider larger steel or concrete solutions. Also, customers expecting metal hardware or integrated lifting mechanisms should look elsewhere.

Pros & Cons

Pros

• Good compatibility with square and round jack feet and common wheel sizes.
• High claimed load capacity gives peace of mind when supporting heavy trailers.
• Stacking groove and moderate weight make it practical for travel and storage.

Cons

• Some customers report mixed impressions about long-term durability under very heavy, repeated loads.
