Video Transcript for Stromberg Carlson Camper Jack - Stabilizer Jack - JB-30 Review

Today, we're going to be taking a look at a Jack-In-A-Box camper slide-out support set. These stabilizer jacks are designed for camper slide outs. They can be used for other applications as well, but they are intended to be used for camper slide-outs. They're going to feature a nice, large view channel here at the top of the bracket. This is going to straddle the frame member for secure positioning. Also you'll notice that the handle does not stick out to the side, it's actually able to be folded down along the upright tube so the folding handle allows the jack to store in smaller compartments without taking up an excess or awkward space around it.

The unit's made from a durable steel construction. It's all steel parts, very strong durable design. The unit's going to feature two different kinds of finishing, so what you see that is black in color is going to have a durable, black, powder coated finish that's going to do a great job lasting a long time, resisting rust and corrosion. It's going to take the brunt of all the hard stuff like scratches, scuffs, anything like that the powder coating does a great job with. On everything else like on everything that looks this silver color, that's going to have a zinc plated coating or a zinc plated finishing and that's going to do a great job as well when it comes to resisting rust and corrosion. Now, these units can adjust anywhere from 31" tall all the way up to 45" tall. It's going to have this threaded like screw and post system, and then the handle's attached to this nut so as you rotate the handle, that's either going to raise or lower the system.

Makes it very easy to do, very easy to get the unit in place. Again, height adjustment ranges from 31" to 45" tall. Each jack is going to be able to support up to 10,000 pounds. That's weight capacity per jack. You're going to get two supports, and when it comes to that U shape right here, that internal measurement going side to side this ways is going to be about four and a quarter. Edge to edge going this direction, that contact area is going to measure 2" wide.

Then the footplate on the unit that's welded to the bottom of the tube, that's going to have a diameter of 4 and 9/16 of an inch. That's going to do it for today's look at the Jack-In-A-Box camper slide-out support set.

My slide out jacks are just what we needed. It helps with the stability of our fifth wheel rv. The delivery was fast and I would definitely recommend this product and this company 792021

Not happy with these. I bought 2 sets (4 jack stands). One of the stands will not adjust. The corkscrew mechanism is faulty, which obviously makes it useless. I found them hard to use and confusing to adjust. There are no directions or instructions in or on the box. Fortunately etrailer has a helpful video on how to use this product. The positives: they seem to be of a sturdy build. They are heavy. And I’m sure they can support the weight as advertised. For me, this was a bad purchase and would not recommend this product. I wish I would have returned them. 746203

These jacks are exactly as described. The video on the website shows precisely how to use them. Very easy to use. These jacks were used on our motorhome slides. Since we do not have the "rod" to place the brackets under, we used a tire "riser" on the top. We also used a board on the ground to help it from sinking into the ground over time. Very pleased at how easy they are to use. The order and delivery process was very smooth and timely. Completely recommend the jacks. 574378

I did not use these for a slide out, I have a pop up tent trailer and I use them to support the bunk ends. They work great, and I sleep well knowing that the bunk has extra support. 546846

I really love the jack stands for my sideout. I had to modify ( shorten) them as the return policy was to ship them back in the original packaging which I no longer had. So the return wasnt acceptable. The product itself is a great item, they do what they were suppose to I love the supports 480749

We bought these for our main living room and kitchen slides while in use at the river for 6 months straight to hopefully help take some of the constant pressure and extra weight off the slides. They worked great and provided a lot stability!! I would definitely buy these again if needed. 386990

Though I haven't used the items yet, I have inspected them. The Jack-in-a-Box Camper Slide-Out Supports seem to be a sturdy product. I can see where the small base could sink into the ground if it is soft or damp. I'll carry something with a larger footprint to put underneath the base plate in case it's needed. The prices are good and delivery was quick. When I need other items for a motorhome, I'll check etrailer.com. 255118

I ordered these jacks for a very unorthodox purpose. They work GREAT !!!! I'm attaching photos if possible . This is a vinyl shed I put up on top of an old pool deck--- there used to be a round above ground pool next to it. Nowadays it's home to about 14 feral cats. The shed replaced a bunch of tarps that used to give protection to the "top" deck layer . The cats use the area under the deck also . I have insulated shelters there and the whole area is filled with fresh straw yearly and there are heated water bowls and birdbaths so the cats can get fresh water even in sub-zero temperatures. The shed gives better protection to the cats than the tarps did but at one point on the deck the shed overhangs the deck a tiny bit because the deck was made in a curve to fit the pool. There was a slight misalignment due to the plastic shed panels warping and/or the deck being not perfectly level and the front doors wouldn't align. Voila ! The jack is a much better option to a wooden 2 x 4 upright and can be adjusted as needed. This was a Godsend: not many adjustable jack stands out there that are over 44" high. Many many thanks from both humans and felines . It's going to be -10 degrees tonight and this structure enables them to make it through the harsh weather. 168993

    Although the Jack-in-a-Box Camper Slide-Out Support Set # JB-30 are meant to be used for supporting a slide out on an RV, I'm sure you could find a way for them to add some extra support in addition to the OEM supports that came on your 2000 Viking Popup. Attached is a review video for you to check out. If you look at some of our customer reviews you can see that they have used these jacks for other purposes as well.

With a support jack, more capacity is a good thing when used properly, so this jack support much more weight than the Ultra-Fab Slide-Out Supports for Motor Homes - 26" to 47" - Qty 2, # UF19-960003 rated for 700 lbs each or 1400 lbs combined.

  • Is Travel Trailer Being Slightly Off Level Normal
    It seems like you are attempting to get your 2019 Forest River Cherokee absolutely level, though you should be focusing on simply getting as level as possible, which is going to depend on various factors like the terrain and your trailer's load, so being slightly off level is normal. For example, you mention it gets more off level when you extend the slide out, which makes sense because the weight is being distributed differently in the trailer compared to when the slide out is not...

  • Recommended Slide Out Stabilizer for Trailer or Motorhome Slides
    The Leveling Scissor Jack Set - 30" Lift - 5,000 lbs - QTY 2 # JSC-30 is not intended as a slide stabilizer but can work in that capacity if your slide is only 30 inches off the ground max. There are specific stabilizers intended for this purpose that may be a better option. I recommend the Jack-in-a-Box Camper Slide-Out Support Set - 20" to 34" Tall - 10,000 lbs - Qty 2 # JB-20 or the 31-45 inch tall # JB-30 rated for the same capacity.

    The Ultra-Fab slide out supports # UF19-960003 will have a combined weight capacity of 1,400 pounds and an adjustable height between 26-47 inches. I like the quick-release handle for extremely easy height adjustment. You simply press the button to release the inner tube and adjust as necessary. I think these will be just fine for your large slide-out. The Stromberg Carlson slide-out support # JB20 or # JB30 both have a 10,000 pound weight capacity per jack. The # JB-20 can adjust between...

  • How To Support the Slide-Out On a 2019 Grand Design Transcend 28MKS
    I do have an option for you but the Valterra Folding Manual Stabilizers part # 020106 are most likely too short for your slide-out. Instead you can use the Jack-in-a-Box Camper Slide-Out Support Set part # JB-20 (if permitted by the manufacturer) as these will reach up to 34" tall and will be perfect height for most slide-outs. They also have a 6,000 lb weight capacity and come with a one year warranty. If your slide out is more than 34" off the ground we have the Jack-in-a-Box Camper Slide-Out...

  • Will Using Front to Back and Side to Side Stabilizers and Jacks Damage the Frame on a Trailer
    Stabilizer jacks such as # UF39-941705 are not meant to do any lifting, just support weight and make it NOT feel like you are on a boat when you move about inside your trailer. So the chance of causing frame damage to the trailer is statistically zero. There is no specific place you have to mount the stabilizer so it can be as near or far from the wheels as it has to be. You will want to place it in the frame where the side to side movement is most likely. We also have slide-out...

  • Slide Out Support For Travel Trailer
    The Jack-in-a-Box Camper Slide-Out Support Set # JB-20 for 6,000 lbs capacity and # JB-30 for 10,000 lbs capacity are rated per jack. So each jack will be able to support 6K, or 10K for a total of 12K and 20K respectively. So both set will have more than enough capacity to handle the slide out on your travel trailer. The # JB-20 can range from 20" - 34" in height, and the # JB-30 is adjustable from 31" - 45", so you'll want to measure to see what height range will work best for you....

You may also be interested in slide-out stabilizers as well like the part # JB-30. This will further help stabilize the trailer by bracing the slide out as well.
