When your setup needs a reliable foundation, these Stromberg Carlson Base Pad Extremes hold strong under pressure. Each pad supports up to 6,000 lbs to help reduce rocking and swaying once you’re leveled. The wide footprint—10" across the top and 12" on the bottom—spreads the load evenly so your trailer or camper stays planted and secure.
Uneven terrain or soft surfaces don’t have to mean instability. Each 7" tall pad can be stacked with another to reach 12-3/8" in height, giving you flexibility when parking on slopes or ruts. Even when stacked, they maintain a solid 3,500-lb capacity per pad, so you get extra lift without sacrificing strength.
Made from lightweight polycarbonate that’s similar in strength to bulletproof glass, these pads are both rugged and easy to move. They resist cracking under heavy loads and handle long-term outdoor use without weighing you down. Side panel finger holes make them simple to grab, carry, and position as you set up camp or store your rig.
With four pads included, you’re set for all corners of your setup. The low-profile design fits under smaller units as well as those with higher clearance, giving you consistent support wherever you park. The muted slate gray color blends in nicely with most setups so your stabilizing gear looks as clean as it performs.

Whenever you get to the campsite, you want to level your camper. Sometimes you have extremely difficult terrain, if you're not going to the normal spot you usually go. So if you do that or you have a manual crank, it's going to save you a little bit of time and effort and just be able to keep this stabilizer nice and stabilized. And with the Stromberg Carlson base pad extreme, this is going to give you a lot more height than some of the traditional pads that we offer here at etrailer. This is saving me a lot of time and hassle just because it's just a decent amount more rotations to get there down in my old pad that was really short, but this one's about seven inches tall and it's about 10 inches wide in diameter on top. So for my eight inch pad right here, it works great.
And it's going to have a lot more surface area and it is made of polycarbonate. So it's basically like bullet proof glass, not going to fade, not going to crack. And it is going to have a 6,000 pound capacity. And the nice thing about it is if you are in extreme situation, wherever you may be, maybe by the river, you can go ahead and take this down here and you can fit it in, stack them on top of each other. With this, it's going to be about 12 3/8 of an inches tall and it is going to break down that capacity to about 3,500 pounds.
As you can see, we have a lot of structure on the inside. So it's going to be plenty strong and it is going to have a 12 inch diameter base. So, it's going to be a little bit bigger than the top, which is good, so it's going to spread that out. Definitely a lot more surface area than what I was dealing with before. And these might get a little slick if you are putting them out or taking them in when it's raining.
So we do have little holes here and you can go ahead and just put your finger in there just so you can carry them around if it's slick, but they're not that heavy at all. They're very, very lightweight and they will stack. So whenever you put them into a storage compartment, you just stack them up, put them in there, done deal. They are kind of bulky. So depending on what kind of storage you're working with, this is going to determine how well you're gonna be able to put them away, but was this, you know, all I need is four, for this whole entire setup so that it doesn't really take up a whole lot of space.
You know, 12 inches on each side, they go up right next to each other. So about two foot wide, two foot long. And then of course, it's going to be about 12 3/8 tall. So it fits in our storage compartment pretty well. You can either just grab one of them for you trailer. You can grab two. We also have kits for quantities of four and of course, quantity of six. So depending on how many stabilizers you have on your rig, you can grab accordingly. Or if you're going to use it on a trailer, we have this little hole right here. This is just going to be for that little jack stand on the front, by your coupler of your trailer. You might be wondering why you would only need one. Well, if you have something like this, regardless of it's a camper or a trailer, you can use it for the center jack, to jack it up. It has a nice little hole in the middle for it to sit down. It's not going to slide around anywhere. And it is going to have a diameter of two 5/8 of an inch. I think there's a lot of benefit to just raising that surface up when you're using a jack like this, just because as this tube starts to go down it gets a little bit more wobbly. So if we can keep it in that tube as much as we can by lifting this up a little bit, that is always going to be a lot more stable. It's easier on your equipment. And if I we're to compare it to one like this, I just liked the bigger base just because, one, it's going to spread it out a little bit more. Two, it is about the same height but I like the looks of this and this just gives me a little bit more peace of mind. Here we have a couple of different options. One reason why I like these is all you need is two have them to stack up and you'll be able to get a lot more. For this we have 1, 2, 3, 4, 5, 6, 7, 8, 9 of them. And we're a little bit higher up, but all we need is two to even get higher up than that. I like this material better and of these two, I definitely like these just because I need less of them and these can get lost and yada, yada, yada. I usually need a decent amount of lift. It's gonna make it easier on me. One thing that this pad has a little bit over this pad is just the fact that you can keep these on your landing pads whenever you're going down the road. You don't have to store them. So if the rubber smell and something you don't want, you can just keep them on. But also if you have these on and need a little bit more lift, you can go ahead and just grab these and it'll work great. So, just getting your trailer/camper level is definitely something you want to do. And we have a lot of different options, but these are definitely ones that I will have and I'll probably use them in conjunction with another pad. And that'll do it for a look at the Stromberg Carlson base pad extreme. And I'm Adam with etrailer..

So far great
Very sturdy. A little on the heavy side
stackable, and they do the job.
These were heavier than I expected and seem to be solid. Very happy with them on initial use.
Great, light and easy to store.
Well made. Fits jacks perfectly. Lightweight and very is to store.
Cumbersome in my small pass through but sturdy and works well.
Shipping was phenomenal!!! The base pads are exactly what we needed!
Awesome product. Light weight and extremely sturdy. More than sufficient for my 13.000 pound Cougar 364BHL. I would highly recommend.
Lightweight and durable option for my travel trailer scissor jacks.
Used base pad extreme for first this week. Seemed to help with the swaying when leveled. Andersen pads are very good to but 9" is to high for rear Jack's and are 2x the money
Been using these for a year and they are amazing. I know you could screw some boards together and accomplish the same thing. These are so light and easy to move. Don’t do that. Don’t be that guy that luggs those heavy blocks around. These are lighter and easier to move around and save you space. They stack onto each other and I have used them doubled up when the back jacks need way more than the front. They have been used on every surface—rocks and gravel are no problem. They’ll hold up. Highly recommend the investment.
I have a 5th wheel & use these base pads, they work great. I feel the trailer is more stable & is faster to set up as the jacks do not have to extend as far.
I would recommend using a piece of plywood under the base to give it a bigger foot print & to help prevent settling or purchase the Jack pads.
The only instance where I do not use the base on the front landing gear is when I have to lower the front when leveling.
I purchased this set as a Christmas gift
Heavy duty but light weight. They are stackable for easy storage. The ones I bought are 9” so they will work well with my 5th wheel leveling system.
Base pads really help stability of your trailer.
Was a little skeptical at first but they really do work great. E-trailer shipped fast like they always do so no surprise there. They do take up some room when storing but at least they stack together. As you can see in my picture, they do stand up to a lot, notice the wheels off the ground.

These are really holding up well, a year now and still like new.
Very good quality and fast shipping
Easy to move around and set up. They also help in preventing over extension of the electric jacks

They have been an asset to leveling my fifth wheel. I bought the four pack because my fifth wheel has six jacks for leveling it up. I don’t need them for the front. It’s adjustable. They are great work good and stackable for storage. forgot to mention they are lightweight if you’re trying to watch the weight in your rig.
