VEVOR Trailer Jack Block, 6000 lbs Capacity per RV Leveling Block, Polypropylene RV Camper Stabilizer Blocks, RV Travel Accessories Use for Any Tongue Jack, Post, Foot, 5th Wheels, 4-Pack

I purchased four of these 8 inch high stabilizer blocks for use in stabilizing and leveling a 26 foot RV. When the package arrived it had visible shipping damage to the shipping box. Upon opening the package, two of the blocks were damaged by a heavy impact on the sides from the shipping process, (not their fault). I contacted there customer support and it was honestly one of the best experiences I have had dealing with a very proactive customer support team. I am not one who is easily impressed, but I was. The package was replaced quickly and arrived undamaged. The product description is accurate, the blocks themselves seem to be very well made. They have an 8 inch height and a solid footprint and relatively light weight with finger holes making them easy to carry. They provide solid stabilization and very good leveling aspects and these blocks do what I need them to do. I think this is a very good product for the money.

Just got a new travel trailer, and I knew I wanted something to put under the stabilizer jacks. I used cinder blocks with my previous RV, but they’re way too heavy and bulky. These plastic blocks are perfect! They’re lightweight, easy to move and store, and they stack! And the price is fantastic! Highly recommend!

Exactly what I needed. I flipped my axles so my trailer is really tall and a lot of shimmy with the stabilizers down. These are solid and very well constructed. Drastically reduced the travel of my stabilizers providing a lot more stability.

I've been wanting a set of these forever. They are replacing a whole stack of wood blocks I've been using for years. They are light weight and very sturdy. It's nice they are stackable not only for storage but also if I need more than one on any corner of the camper to keep the stabilizer jack from being over extended.

Purchased these so I wouldn’t have to carry multiple blocks of wood, it’s a lot easier to handle just 4 pieces as opposed to 8-12 smaller blocks of wood. They are very sturdy, but moderately heavy. I’m sure they need to be that way to handle the weight they are holding, but consumers need to be aware. I did place a small loop of rope on them to make it easy to retrieve after use. I would say they are worth the investment.

Great quality and price... but I was surprised when I opened the box. These are huge! I got these to go under the stabilizer jacks of my humble travel trailer, but these are definitely robust enough to use on a big fifth wheel, or as a block for the main jack. In fact, they're bigger the a Ox-Block I had for the main jack on my previous trailer and that block cost almost the same as getting FOUR of these! So, I think I'll save a little money and not buy a main jack block and just use one of these, and then I'll use the other two or three on whatever stabilizer jacks have the farthest reach.I think they are priced perfectly, but compared to the competitors, they're an outright steal!

Strong and perfect, what I like most about these is that they are black , not bright yellow or orange and stickers come off easy

I really like these because they are very tall and stackable. They were priced way under the competition. I think I paid about $40 for the set of 4. Good value compared to anything else I could find. My only critique would be that there is no drain hole where your jack fits into. Water accumulates in there and could rust your jack. I just drilled a hole in it. Easy fix.
