Video Transcript for Camco Leveling Blocks - Stackable Blocks - CAM44525 Review

Today, we're going to be taking a look at part CAM44525. These are the Camco FasTen RV leveling blocks. They do come with a carrying handle and towards the end of the video, we'll stack them and show you how easily they can be converted to be in a storage compartment, or how they transform for compact size and easy carrying or transportation. Now, these blocks are going to feature an interlocking, stack-able design. That way they can sit easily under the RV wheels for extra lift. One of the things I want to point out is that these are going to be called four-by-twos. We have four stack blocks going this direction, so this is one block.

You can see these raised areas here, four going this direction, two going this direction; so four-by-two. These are wide enough for those side-by-side wheels that some trailers or campers have. It would work perfect for those situations. You can position these beneath your jacks, your stabilizers and trailer wheels. Again, they do have the interlocking design so that's going to ensure that the blocks won't shift as you drive up on them, or once you're already on them. They're made from a polypropylene plastic, very strong and durable. You do not have to worry about these things caving in, or drooping, or curving, or breaking, or cracking.

They're very strong, and they're very durable. The product is made right here in the USA. With this part number, you're going to get this entire kit. You're going get 10 leveling blocks. Now, we're going to take a measurement of the blocks. They're all going to measure identical. Overall length, from edge to edge right here of the leveling block, we're looking at about seventeen inches. Then, the width of the leveling block, we're looking at about eight and a half inches.

Now, each block is going to measure an inch and a half thick, and then each block is going to provide one inch of lift. Now, when using this system, you want to make sure that you do not exceed a total height of four and a half inches. I've got them positioned in a very common way right here. What's neat about these is you can use these in any configuration that works for your application. You can add or remove, or redesign the stack design to best fit your needs. What I'm going to do right now is I'm going to move it to the stored position so that way you can see what that looks like. In order to do that, we just need to go ahead and get all of them stacked on top of one another.

Now, these are going to be dark gray in color. There is one block that's completely black. That's going to be the block that needs to go on the bottom of the stack. The reason being is because right here in the center, it's got a threaded hole, and it's going to come with this T-handle that comes with threads at the bottom of it. So this T-handle is going to go through the center of all the blocks, like this. What we can do is we can use this as a carrying handle. You thread that down until it gets tight, so you can use it as a carrying handle to transport the blocks. It's going to hold them all together, or, what you can do is you can push that down and now it's ready to be moved to compact storage in a storage compartment, or whatever area you want to store it in. Now with it fully stacked like that, it's going to give us an overall height measuring from bottom to top, it's going to be about ten and a half inches tall. That's going to do it for today's look at part number CAM44525.

Shipping quickly and packaging superior.


As always etrailer has fast shipping with communications to me about shipping. Product is as advertised with good packing.

I will use these for my Class A Motorhome to help get it within leveling range of my airbags as I camp a lot in state, county, and city parks where the camping sites are not very level.

So dont let that great spot get away because it is out of level, always keep these on hand.



These have not held up as good as I would have hoped for. After a couple of uses I have 2 that have broken and now it is hard to get them to stack correctly and fasten them all together for storage.


I have a Thor Magnitude with a GVW of 19,500 lbs. I have used these under the tires to get a rough level before using the jacks. The extra size is needed to fit the dual rear tires. These blocks are strong enough to take the load. I definitely recommend them for people with larger rigs.


We love these leveling blocks. They fit perfect under the dual rear wheels of our Class C motorhome. They are also nice to use on the front wheels. By turning them parallel to the tires, the wheels are not balancing on such a small area, so leveling the front feels more secure.


These blocks are great! We have a 40 foot Tiffin RV and occasionally we need a little more height and don't like the wheels to come close to lifting off the ground. We use these extra large blocks to drive up onto. Then we do auto level. We've only used these once, but they seem to handle the weight well. So far no complaints. I even may buy another set so that my jacks will have a wider foot print to sit on. We have had issues with very soft earth and the jacks just sink. These blocks should help a lot with that.


I love these block. The stack is not too heavy to handle for 135 lb 59 year old female. Blocks work great for all wheels of our class C motorhome. They can be turned either direction which is great for rear dual wheels or turned long wise to give extra surface for the front wheels.


These are a little lightweight for use under the front wheels of my 23' Class C (where the motor is) and tend to squish if the ground is uneven. Once they do that once, it's tricky to assemble them again because, like Legos, the fit of one to another is quite precise and if they get deformed it's a headache. Probably better suited for a lighter-weight application, or a very stable surface underneath. Thinking of carrying a short 2 x 10 to use as a base.


Works great for those sloped sites you encounter. Enough of them to provide a ramp up for one side of a dual axel trailer.



Great. Needed in many areas I camp.


These blocks are great. We use them on the dual wheels on our class C motorhome and on the front wheels if needed. They do not bend and cup like the smaller size lesser expensive blocks. They are very sturdy but not to heavy for me, 58 year old small framed woman to handle.


These work perfect, makes leveling effortless. Very durable, sizing is spot on



These work great, very durable, storage is well engineered.


Great most of the time. When using on slightly uneven surfaces they are a bit flimsy. All in all, good product.


We really appreciate the prompt delivery and email attention to my order. I have not had an opportunity to use the leveling blocks yet, however, the Husky Liners-HL33251-fit our new Ford E series RV perfectly and we are very happy with them.


While I have not used the leveling blocks, they seem to be well made and very easy to use. They are light weight and the carrying handle is great and contains them for storage. My only concern is weight capacity as it is not stated? Very fast shipping and delivery (free).


This product arrived on time and in excellent condition. I haven't had a chance to use the leveling blocks just yet but will be glad I have them when needed.


Love these! I was using cement blocks for a while and am so happy I was able to find these to replace them!
The stackable blocks with the handle are perfect!


Solid product. So far not one has cracked as I stack to level my truck. Sometimes I have to fiddle with to get to stack together but that usually means I'm rushing.


We needed the larger blocks for our motorhome since it has dual tires on the back. These work great


Great product easy to use with etrailer it is easy to order and fast service will use etrailer again


They look nice but I think I need an additional set for the tandem wheels on my trailer.


This was a perfect purchase. Item was as advertised and fits to perfection. Transaction was a breeze and E Trailer easy to deal with. Thanks E Trailer


Very happy with these levelers and the way they stack together


Great, fast service. This is a new adventure with camping. Got our first camper. Haven't gotten to use it for a trip yet, but found some great, helpful gadgets.


They are working out great, thanks for checking in.


Just exactly what is supposed to and that's all you can ask


Haven’t used them yet so only 4 stars. Arrived in good condition, was back ordered and got an email as soon as they came in.
