They’re about the size of leveling jack pads. These blocks are big enough for small trailers, but they aren’t large enough for class A trailers. The plastic itself won’t fade or degrade on exposure to sunlight for years. Being plastic, it won’t rot or attract bugs like the conventional wood boards used for this purpose. The only exception is the round recessed spot in the middle, though this can’t hold much water. If you overload them, the interlocking connections could break and then they’ll slide around at will.Ĭonversely, the closed blocks won’t sink in the mud or capture water the way some of the other products on our list of the best RV leveling blocks would. This means that they’ll stay in place if you’re lowering the side of a trailer onto the stack while you change a tire, but it may not stay in place if you have three holding up a wheel and the stack gets kicked or simply shifts.
The Model 44573 cannot be used for a double axle trailer at all, because there’s no space between the wheels to put them.Ī minor issue with these blocks is that they won’t necessarily stay nested if subjected to off-balance pressure. That model would be better for a double axle trailer than the Model 44573 leveler. The “super” model of this product costs up to twice as much, but it is rated for up to three times the load.įor most people, these RV leveler blocks are good enough, as long as you’re driving a smaller trailer. They have a load capacity of 3500 pounds. See our other listings to find RV levelers that can act as chock blocks. They tend to slide on wet pavement, too, when you try to drive up onto them. You should only use them on concrete or flat pavement, because they will otherwise sink into mud and gravel. The downside is that the product isn’t very wide you have to locate it precisely to have it work properly. You can put the leveler in front of or behind the wheel and drive onto it. One point in its favor is that it can handle almost any size tire, since it is an open design. Don’t try to put them over a pothole and then drive over them, either.
The problem is that when you put them on an uneven surface like gravel or rocky ground and do the same, they’ll break. They’re designed to be laid down on flat pavement before a vehicle drives up and onto them or over them. One downside with their design is that they don’t handle uneven pressure well. The group of ten costs a little under seven pounds. They come with a basic plastic storage bag. If the material is breaking down like this, it will shatter under load.

If you have it outside in -20° weather, it will crack and even chip though it isn’t under load. The plastic will do fine in the summer sun and barely freezing weather. However, the plastic can’t handle extreme cold. It is far better than using a board for the same purpose. The plastic is UV resistant and water-proof. These versatile loading blocks can be connected to support a tire or cover up a hole, and unlike the Tri-Lynx, you can drive over them.
