Product is as advertised and works very well for supporting trailer jacks as well as minimizing front jack extension lengths.

These TOWKING RV stabilizer blocks are super handy to have! For storage, they sandwich together and fit into a nice carrying bag. They are strong and sturdy but relatively lightweight for ease of carrying. Each has a little rope handle that you can use for carrying and moving. They work well even with stabilizer feet that aren't round, as shown in my pictures. They help the RV with stability, and I don't have to lower my stabilizers down as far with these guys underneath them. Really convenient tools and very well made. Highly recommend!

I ordered these leveling blocks to replace a homemade set I have been using on my travel trailer. Here are my likes and dislikes for these blocks: Likes: - They are lightweight but strong. - The rectangle base scissor jacks on my travel trailer fit solidly on the blocks. - They are made of plastic so I don't have to worry about them getting wet like my homemade wooden blocks. - The blocks have a divot so they can be used on the tongue jack as well as the stabilizer jacks. - They have both a handhold slot and a cord. The cord helps to make them easy to pull from under the camper. - They come with a nice storage bag. The zipper on the bag is easy to close when all blocks are put inside, not too tight or too losse. Dislikes: - The blocks don't interlock when stacked. Overall I find these to be a nice set of blocks that I will use with my trailer's stabilizer jacks. The one dislike I have is minor.

For our YouTube travel channel, we use jack blocks constantly to support both the scissor jacks and the hitch jack on our travel trailer. Finding reliable support that isn't wildly over-rated is key, and these TOWKING blocks seem spot on. The biggest selling point here is the 12,000 lb capacity. Unlike other blocks claiming absurd ratings, this number feels honest and is more than enough support for our setup. I confirmed the stacking feature works perfectly—the blocks lock very securely together to transition from the base 6" height. When stacked, the load limit drops to 6,000 lbs, which is still more than enough for us. The design is well-executed for RV use. I like the ergonomic finger holes and the small rope that makes grabbing them out of the truck bed easy. However, that same carrying rope can get a bit fiddly when you are trying to stack them tightly; it's a minor hurdle, but something to be aware of when packing up quickly. While I didn't test the anti-tilt cone base and 8 ribs on mud with this specific set, my experience with virtually identical blocks confirms they perform well on uneven ground and give us that zero wobble feel we need when leveling. They are a heavy-duty, practical system for any trailer owner.

These 6-inch Heavy-Duty Trailer Jack Blocks are exactly what I needed for my travel trailer. Each block feels solid and well-built, and you can tell right away they’re made to handle serious weight. With a 12,000 lb capacity, they easily support my trailer without any flexing or wobbling. I’ve used them on gravel, asphalt, and dirt, and they stay stable every time. The 6-inch height is perfect for reducing the number of crank turns on the jack, and it saves a lot of setup time at the campsite. The flat, wide base keeps everything secure and prevents the jack feet from sinking into soft ground — a big improvement over wood blocks or plastic alternatives I used before. They also stack neatly for storage and don’t take up much room in the RV’s compartment. I really like that this set comes with four blocks, so I can use them under stabilizers, tongue jacks, or leveling jacks depending on my setup. The bright color makes them easy to spot at night or when packing up. Overall, these are heavy-duty, durable, and well-designed jack blocks that make setting up and stabilizing your RV or trailer safer and easier. Definitely worth the investment for any RV owner looking for long-lasting support gear!

We got these to use on our upcoming Super C, so we will have the room to store them. We tried finding a spot in our current travel trailer but storage was too limited. They aren't overly heavy, just bigger than the room we have currently. These blocks are extremely well made and I have no doubt that they will work on our 20k towing beast. The height on them is kind of that goldilocks height. Not too tall and not too short. Functionally, these will be great to keep the levelers off the ground and still be very solid. Overall, really happy with these blocks!

I ordered this set of four 6” jack blocks to use with automatic levelers on a motorhome. It seems that most suppliers of these blocks are going to this type of material and similar design because of the strength and value provided. These jack blocks also appear to be well engineered and constructed to provide the strength necessary in a variety of RV applications. They also come with a carry bag for convenience, as they tend to get dirty if used off the pavement. I will be using these blocks for purposes other than I intended, because the 6” blocks only fit under my rear levelers, not the front. I’m sure the 4” set would have worked well under my RV. Be sure to measure your application. The price when I ordered was $86.99, a very good value. The 4” set, although not stackable, also a very good value at $76.99.
