Buying Guide: How To Choose The Right RV Slide Out Supports
What height range do you need? Most RVs require supports that span roughly 15″ to 50″ when fully extended. If you frequently move between campsites, prefer models with faster drill-assisted height adjustment for quicker setup. For permanent or longer stays, consider steel construction with rust resistance and larger contact surfaces for stability.
How much weight must they support? Choose a system that offers at least 5,000 lbs per jack if you have a standard travel trailer. Dual-jack configurations provide balanced support and reduce sway when parked on uneven ground.
What installation and operation style suit you? Drill-assisted models save time but require a compatible drill. Manual crank or lever systems work well if you travel light or want a simpler setup without power tools. Reversible top plates increase compatibility with various slide-out rails.
Where will you place them? If you frequently park on grass or soft soil, plan for leveling blocks or pads to prevent sinking. For concrete pads, ensure the top blocks align with your slide-out frame to maximize contact area.
Durability and finishes matter. Look for powder-coated steel or galvanized components to resist rust, especially in coastal or humid environments. A robust, stable contact block reduces wear on slide-out rails over time.
