Why Slide Out Supports For RV Are Necessary
From my experience, having slide out supports for my RV is absolutely essential. When I first started using my RV’s slide outs, I noticed they tended to wobble or sag slightly when fully extended, especially on uneven ground. Slide out supports provide that extra stability, making the entire living space feel more secure and comfortable. Without them, I often felt the walls shifting just a little, which can be unsettling during the night or when moving around inside.
Another reason I rely on slide out supports is to protect the mechanical components of the slide out itself. These supports help distribute the weight more evenly, reducing strain on the motors and rails. Over time, this means fewer repairs and less wear and tear. I’ve found that investing in good slide out supports has saved me from costly maintenance down the road.
Lastly, slide out supports give me peace of mind. Whether I’m parked on a slight incline or a soft surface like gravel or grass, I know my RV’s slide outs won’t sag or become misaligned. This stability is crucial not only for comfort but also for safety, especially when multiple people are inside. Overall, slide out supports have become one of my must-have accessories for a hassle-free and enjoyable
My Buying Guides on Slide Out Supports For Rv
When I first started looking for slide out supports for my RV, I quickly realized how important it is to choose the right ones. These supports make a huge difference in stability and comfort when my RV’s slide-outs are extended. Here’s what I learned along the way, which I hope will help you make a great choice too.
Why Slide Out Supports Matter
My RV’s slide-outs add valuable living space, but without proper support, they can wobble or sag. This not only feels unstable but can also cause long-term damage to the slide mechanism and seals. Slide out supports help keep everything steady and secure, so I can relax inside without worrying about wear and tear.
Types of Slide Out Supports
I found there are mainly three types to consider:
- Manual Supports: These are usually simple jacks or braces that you set up yourself. They’re budget-friendly but require some effort to install each time.
- Electric or Powered Supports: These make the job easier by extending or retracting with the push of a button. They’re more convenient, especially if you have multiple slide-outs.
- Hydraulic Supports: These offer smooth operation and strong support but can be pricier and might need professional installation.
Key Features I Look For
When shopping, I focused on these features:
- Weight Capacity: Make sure the supports can handle the weight of your slide-out. I always check the specs to match or exceed my RV’s requirements.
- Durability and Material: I prefer steel or heavy-duty aluminum supports that resist rust and corrosion, especially since I often camp in wet conditions.
- Ease of Installation: I looked for supports that I could install myself without special tools or modifications.
- Adjustability: Slide-outs can vary in size, so having adjustable height and length is crucial for a perfect fit.
- Portability and Storage: Since I have limited space, I chose supports that are compact and easy to store when not in use.
My Top Tips for Buying Slide Out Supports
- Measure Twice, Buy Once: I made sure to measure my slide-outs carefully before making a purchase to avoid any compatibility issues.
- Read Reviews: Hearing from other RV owners helped me avoid models with common problems and find ones that hold up well over time.
- Consider Your Usage: If you frequently move or extend slide-outs in different terrains, investing in powered or hydraulic supports made more sense for me.
- Check Warranty and Support: I picked brands that offer solid warranties and customer service, just in case.
Final Thoughts
Choosing the right slide out supports for my RV has made a noticeable difference in comfort and peace of mind. Whether you’re a weekend camper or a full-timer like me, investing in quality supports protects your RV and enhances your experience. Take your time to evaluate your needs and preferences, and you’ll find the perfect fit.
I hope my buying guide helps you feel confident in picking the best slide out supports for your RV adventures!
