Sturdy, Simple, and a Must-Have for RV Leveling!
Style: Levelers, Size: 10 Pack
The Tri-Lynx 00015 Lynx Levelers have been a fantastic addition to my RV setup, especially for stabilizing the jacks. These levelers are durable, easy to use, and provide great support, whether I’m parked on gravel, grass, or an uneven surface. Here’s what I love about them:
Design and Durability:
These levelers are built tough! The bright orange color makes them easy to spot, and the interlocking design is straightforward yet very effective. I feel confident stacking them to the desired height, and they stay solidly in place without any shifting or sinking, even under the weight of the RV jacks.
Ease of Use:
One of the best features is how simple these are to set up and take down. They stack quickly and neatly, and I love that I can easily adjust the height by adding or removing levels. They’re much more convenient than traditional wood blocks, and they don’t splinter or deteriorate over time.
Versatility and Stability:
I’ve used these levelers on different types of surfaces—gravel, sand, and even on slight slopes—and they’ve performed well across the board. The stability they provide gives me peace of mind, knowing that my RV is secure and won’t shift during the night. They work great with the jacks, keeping everything stable and level.
Storage and Portability:
The carrying bag that comes with the pack is a nice bonus, making it easy to store them compactly. The pack of 10 is perfect for my needs, providing enough flexibility to handle different setups depending on the terrain.
Small Points for Consideration:
One small note is that these levelers may require a bit of experimentation to get the exact right height when stacking. It’s minor, but worth noting for anyone new to using leveling blocks. Once you get used to the setup, though, it’s smooth sailing.
Final Verdict:
The Tri-Lynx 00015 Lynx Levelers are a must-have for any RV owner. They’re durable, stable, and incredibly easy to use, making leveling and stabilizing a breeze. I’d recommend them to anyone looking for a reliable solution to keep their RV perfectly level and secure. Great value for the price!
