The following sections detail each product’s strengths, who should buy it, and practical considerations to help you decide which is best for your RV and campsite conditions.
LUSHIH RV Slide Out Support Jacks
Best for budget-conscious campers with smaller slide-outs. Each jack lifts up to 5,000 lb and offers a travel range of 15 to 26 inches, with a stable 5.94″ x 2.95″ top surface to fit most slide frames. The design uses heavy-duty steel with zinc powder coating for rust resistance. A caution: a wood 2×4 block is recommended on top to protect your trailer’s frame when real-world uneven surfaces are present.
Kohree RV Slide Out Support Jacks (Flat Top)
Choose this if you want a flat top design that eliminates the need for extra blocks. The 20″–49″ height range supports a wide array of rigs, up to 20,000 lb for a 4-pack set, and operation can be powered with a drill or hand crank. Best for larger trailers that benefit from a stable, wood-free top interface. A potential limitation is needing a compatible power drill and socket for fastest adjustments.
VEVOR RV Slide Out Support Jacks
Best for a balanced, two-jack setup to stabilize mid-to-large RVs. Each jack supports up to 5,000 lb, and a robust 20″–48″ height range accommodates various ground clearances. The system encourages using leveling blocks on soft ground and features straightforward adjustment via a folding handle. A practical note: two-jack configurations may still require supplemental blocks on uneven or soft surfaces.
Kohree RV Slide Out Support Jacks (4PCS)
Best for heavy-duty, full-time RVers and large fifth wheels. Four-jack systems provide up to 20,000 lb total capacity, with a 20″–49″ height range and a power drill-assisted quick raise/lower function. The flat-top design again minimizes the need for additional blocks. Limitation: requires a compatible drill setup or hand crank tool and extra storage for four units when not in use.
Garvee RV Slide Out Support Jacks (Set of 4)
Ideal for larger rigs that need high-capacity stabilizers. Each jack supports up to 5,000 lb with a 21.1″–49″ adjustable height. The package includes a crank handle and a magnetic socket for drilling, facilitating quick adjustments. Consider this option if you routinely park on uneven surfaces and require robust, uniform support across a set of four jacks.
Buying Guide
- Capacity needs: For small to mid-size trailers, 5,000 lb per jack is usually sufficient; for large fifth wheels or Class A rigs, opt for 4-piece sets delivering up to 20,000 lb total.
- Top design: Flat-top tops reduce the need for extra wooden blocks; if your setup uses everyday blocks, a standard top will still work with caution.
- Height range: Ensure the recommended 20″–49″ range covers your RV’s ground clearance and leveling needs; some models start at 15″ while others exceed 50″ in rare setups.
- Adjustment method: Power drill compatibility speeds setup; hand crank provides redundancy in case of drill failure or battery issues.
- Surface considerations: Use leveling blocks on grass or soft ground to prevent sinkage and ensure stability on uneven terrain.
- Block-on-top necessity: Some top designs assume a wood block; others recommend flat, block-free tops—choose based on your slide-out frame and installation space.
FAQ
- What is the typical purpose of RV slide out supports? They stabilize and lift the slide-out section to prevent sway, particularly on uneven or soft ground.
- Can I use these with any RV slide-out? Most are compatible with common slide-out frames, but always verify the top surface design and height range for your model.
- Do I need leveling blocks? On soft ground or steep angles, leveling blocks improve stability and protect the jacks from sinking.
- Are four-jack sets better than two-jack sets? Four-jack sets distribute weight more evenly, reducing sway on large slides and heavier RVs; two-jack sets are often sufficient for smaller rigs.
- How do I know if I should choose flat-top or standard top? Flat-top tops simplify block-free setups and are preferred for newer frames; standard tops work well with compatible blocks on older frames.
