Camco RV Leveling High-Gain Bases, 2-Pack Nesting Stabilizer Jack Platforms — 8,000 lb Capacity, Carry Handle

Camco FasTen RV Leveling High-Gain Bases are heavy-duty nesting foundations that give stabilizer jacks a secure, elevated platform so your RV stays steady on uneven or soft ground.

When campsite terrain is soft, sandy, or too uneven for a jack foot alone, these FasTen Big Blocks create a wider, more reliable contact point that protects both the jack and the vehicle. Designed to accept 2x2 square leveling blocks and compatible with Camco FasTen stabilizer jack pads, each base supports up to 8,000 pounds and nests together for compact storage. The integrated twist-lock carry handle keeps the pair together and makes transport simple, so you can leave bulky improvised solutions at home.

How do these bases improve stability on soft or uneven ground?

The wider footprint spreads the load from a small jack foot across a larger area, reducing sinking and rocking. That translates to a safer, steadier setup for camping, maintenance, or overnight stays where firm surfaces aren’t available.

• 8,000 lb capacity per base handles most RV stabilizer loads.
• Large contact surface prevents jack feet from sinking into soil or gravel.
• Compatible top surface accepts 2x2 square leveling blocks for extra height.
• Use alone or stacked with camper leveling blocks for custom solutions.

Will these work with my existing leveling blocks and jacks?

Yes — the FasTen High-Gain Bases are made to pair with 2x2 FasTen leveling blocks and many square blocks from other brands. They also fit FasTen stabilizer jack pads, giving you flexible compatibility with your current gear.

• Top geometry fits standard 2" x 2" square blocks.
• Designed to accept common RV stabilizer jack feet.
• Integrates with FasTen Large Jack Pads for added protection.
• Works alone when height is not required or stacked for added lift.

How do they store and transport when not in use?

The nesting design lets both bases fit compactly together, saving space in your storage bays or garage. A twist-to-lock carry handle secures the pair for easy hauling, so you’ll spend less time wrestling with awkward pieces when moving between campsites.

• Bases nest together to reduce storage footprint.
• Integrated carry handle twists to lock the two units together.
• Durable construction resists wear from repeated use and transport.
• Light enough for one person to carry yet sturdy enough for heavy loads.

How durable and safe are these for long-term use?

Manufactured for rugged RV use, the FasTen Big Blocks are built to tolerate repeated compressive loads and outdoor exposure. Their sturdy design offers a dependable platform that resists cracking and deformation under typical RV stabilizer pressures.

• High-strength material designed for outdoor and campsite conditions.
• Supports up to 8,000 pounds per base under stabilizer loads.
• Resists crushing and bending that can occur with thinner pads.
• Engineered to protect jack feet and extend equipment life.

Who is this for: Campers, motorhome owners, and towable RV users who need a reliable, space-saving solution to stabilize their rigs on soft or irregular ground. These FasTen High-Gain Bases are ideal for anyone who already uses square leveling blocks or stabilizer jacks and wants a compact, durable platform that nests for storage and travels easily with the RV.
