OULEME RV Leveling Blocks 12-Pack — Stackable Interlocking Pads with Carry Bag, UV-Resistant Polypropylene

OULEME 12 Pack RV Leveling Blocks are a stackable, interlocking set of durable polypropylene pads that let you quickly raise and stabilize campers, trailers, and jack stands to achieve a level setup at any campsite.

When you park a travel trailer or motorhome on uneven ground, a reliable way to raise and support wheels and jacks matters for comfort and safety. These OULEME blocks come as a 12-piece kit (10 interlocking 1.5" blocks plus 2 thinner top pads) that stack to the height you need and lock together to prevent slippage. Built with UV-resistant polypropylene and reinforced thickness, the blocks resist weathering and compressive forces so they last through many trips.

How do these blocks make leveling a camper faster and safer?

The interlocking profile keeps stacked sections aligned under load, reducing the chance of shifting while you crank jacks or park on a slope. Because each base block is uniform in size and has predictable height, you can build a stable platform quickly without guessing stack combinations.

• 12-piece kit: 10 interlocking blocks + 2 thin top pads for a secure contact surface
• Consistent 1.5" block height and 0.7" top pad for precise adjustments
• Anti-slip interlocks maintain alignment under weight
• Made from reinforced polypropylene with anti-UV additives for weather resistance

Will these blocks support trailer jacks, stabilizers, and appliances?

Yes — they’re designed as multi-use support pads for a variety of RV and towing needs. The increased density and thicker structure distribute weight across a wider footprint, so jacks and stabilizers sit on a firmer base and are less likely to sink into soft ground.

• Wide 8.5" x 8.5" surface spreads load under jacks and stabilizers
• Stackability adapts to different jack lengths and uneven terrain
• Durable material handles repeated compression without cracking
• Thin top pads provide a snug saddle for jack heads and wheel chocks

How do I choose stack height and arrange the blocks correctly?

Start with a single block under the jack or wheel and add blocks until the chassis is level using a bubble or digital level. Use the thinner top pad for the final adjustment or when you need a lower-profile contact surface between the jack and block.

• One block = 1.5" height; top pad = 0.7" for fine-tuning
• Interlock blocks so ribs face and engage for stable stacking
• Place larger stacks on firm ground or use a plyboard under the bottom block on very soft soil
• Consider symmetrical stacking under wheels and jacks to distribute forces evenly

How durable are these blocks and how do I store them when not in use?

Constructed from polypropylene with UV-aging additives, the OULEME blocks resist brittleness and fading from sun exposure. After use, rinse off dirt, let them dry, and store the set inside the included carry bag to keep them organized and protected between trips.

• Polypropylene material resists water, oil, and outdoor exposure
• Thicker walls and increased density reduce deformation under load
• Lightweight design makes it easy to carry and reposition by hand
• Includes a compact carrying bag for tidy storage and transport

Who is this for: The OULEME 12 Pack RV Leveling Blocks are ideal for RV owners, travel trailer users, and anyone who needs a repeatable, portable solution for leveling and supporting jacks, stabilizers, and other underbody supports. If you camp on mixed terrain, tow frequently, or want a durable, stackable system that fits in a storage compartment, this kit provides a practical, long-lasting option.
