Will Flexco Pull-Out Steps Work for You?

Pull-out steps are typically installed on travel trailers. The Flexco pull-out steps from Stromberg Carlson are easy to install and fold up underneath the camper for simple storage. To ensure you choose the correct size for your application, there are a few measurements you will need to take.

Mounting Bracket Stromberg

The Lippert pull-out steps attach to the underside of the camper chassis, directly beneath the doorway. To decide which size you'll need, locate the space available underneath your camper that lines up with the door frame, and measure the width and depth. You will need a mounting space that is at least 28-1/8" wide and 12" deep.

If it turns out you have more or less space beneath your doorway, there are other step assemblies available with bracket sizes ranging from 21-1/16" wide to 28-1/4" wide. A full list of the available steps is below.

Outriggers for RV Steps

Outriggers - metal brackets that act as an extension (LC301704 - sold separately) - may be needed for installation depending on the model of your original stairs. These provide extra length if the old steps are longer or wider than the new.

Once you know where the mounting bracket will go and what size mounting bracket you need, that spot will be used as the "mounting point" to determine how many steps you will need.

How Many Steps Do You Need?

Entry Height Stromberg

To determine how many steps you'll need, measure from the mounting point to the ground. This is called the entry height. The entry height should roughly match the height of the steps when they're fully extended, plus 3" to 9" to account for the drop from the bottom steps to the ground. This measurement will also tell you how many steps you need.

The chart below displays mounting bracket width measurements in the first column and entry height measurements in the second column. The third column shows the corresponding part numbers. Use the mounting bracket width and entry height measurements you took to determine which part number will fit your RV. Choose the bracket size that is closest to your measurements without going over.

This page's step assembly is in bold text.

Mounting Bracket Width Entry Height Part Number
21-1/16" 14-1/2" - 17-1/2" SMFP-1120
23-5/8" 19" - 22" SMFP-2120
24-1/4" 10-1/2" - 13-1/2" SMFP-1220
25" 14-1/2" - 17-1/2" SMFP-1100
26" 19" - 22" SMFP-2100
27-1/8" 30" - 33" SMFP-3200L
28-1/8" 26" - 29" SMFP-3100
28-1/8" 34" - 37" SMFP-4400
28-1/4" 10-1/2" - 13-1/2" SMFP-1200

How Do You Install the Steps?

To install the steps:

  1. Make sure the camper is level on flat ground
  2. Lift the steps into the mounting space and prop into place
  3. If needed, mark the mounting holes on the camper and drill

    -Set aside steps before drilling

  4. If needed, install the outriggers
  5. Align step mounting holes and secure in place with carriage bolts and flange lock nuts

    -Make sure the bracket is backed up fully against the I-beam on the chassis

    -Hardware not included

  6. Tighten hardware until snug
  7. Make sure assembly is sitting square and level
  8. Torque the hardware tight

We received exactly the item we ordered in the timeframe we were quoted. Since time was a factor in receiving and then replacing, my husband and I were pleased when the item arrived even sooner than we anticipated. We were able to replace the old item with the new item without any complications. etrailer is now our “go to” company for all of our camper/camping needs.



Like brand new. We will be replacing the second door steps with the same product this camping season.


The hole placement was a little different. Couple quick portable drill mods and the steps were in quickly. The shipment was quicker than expected. Quality of the product was perfect. Staff was very helpful. I highly recommend etrailer.

Still hanging in there. It has held up under all the comings and goings.


These Stromberg-Carlson Flexco Manual Pull-Out Steps for RV'S - Triple - 8" Drop/Rise - 24" Wide - 350 lbs - SMFP 3100 we ordered from were the exact ones that came on our 32.5' 2014 Windjammer trailer by Forest River when we purchased it new. The original steps got bent when we were forced off the shoulder of the highway, causing the rear axle to drop over the edge of the road and drag on the pavement about a short distance before we could stop, bending the stairs and making it nearly impossible to lower them. Fortunately, the mounting brackets were not comprised or bent. Once we placed our order, we received the replacements from in just a few days. My husband had them installed in short order. They look great, and match the stairs at the other door perfectly. The price was very reasonable and customer service very helpful, pleasant and courteous. We would recommend this product and without hesitation.07p


I couldn't be any more satisfied with the new steps, or the help Angela provided me in the selection. The steps were a perfect match for the damaged ones on my 2008 Heartland Sundance. Used a floor jack to hold them up in place, 4 bolts to the main support bracket, 2 bolts to the back braces, and it was done in less than 3o minutes. Please see the pictures.


The new steps were indentical to the old ones except they were not bent up like the old ones. I had to straighten up a bracket that the steps bolted onto. Once that was done they fit right on. It is difficult to get the carriage bolts started because on space limitations. Other than that it not that difficult. The new steps fit great.



The steps work fine. I had to do some straightening on the brackets that hold them in place to get them to retract properly. Bent brackets not a problem with the steps. Still working fine.


Prompt service and product fits well. Stairs seem to be a little harder to use and not quite as stable as original. Stairs are overall a good product for the price.

Jay R.


Same as before.....the stairs fit well, but are not as easily used as the originals


Perfect replacement steps for your 5th wheel... Easy to install. Great customer service and delivery.



Excellent product.


I built a shooting house on a trailer that was 30 inches from the ground. I needed the steps to get into the back door of the shooting house, which is on wheels. If I need to move it, fold up steps was the way to go. I also needed fold up steps as the house is sitting on four jacks, one on each corner for total stability. They also fold up if I need to move the house. The steps allowed me to fold up the jacks without
interference from the steps. The steps are exactly what I needed for this project.
The steps support me as I hoped they would as I enter the house. An excellent product.


Product was exactly as described. Very good quality and was easy to bolt up and replace my existing steps. Would buy products from this company again.



Yes the item works great. We thank you for your help! Still using the steps and the camper!


This product was completely described and accurate. The measurements were given in enough detail that I knew it would fit my trailer and attach easily. Would certainly buy from this supplier with future needs.

Dennis S.


Cant say now as I have replaced the RV.


It would have been nice if you spend $xxx that you would have gotten the mounting brackets with your item. Very disappointed.

If you are talking about the outriggers, they are, at times, not needed, which is why they are sold separately. The item you need is item # LC301704.


Replacement of my travel trailer steps. Installed the mounting hardware from the old steps on the new steps. With the help of a floor jack it only took 10 minutes to install. They work and fit great.


Although product was acceptable it was not OEM dimensions even thought it was produced in 2016. Additionally, the stabilizer jack is small, rinky-dink, and of little use for the application advertised by manufacturer.

Of course these issues do not diminish the outstanding serviced I received from My representative could not have been more outstanding and helpful. The order was processed, shipped and delivered in just three days and my representative stayed in constant communication throughout the process. I encourage all friends and the RVes of America to use this companies service. GREAT JOB


The steps were a dead on replacement, bolt hole wise, for my old steps. I also must say they are much stronger and sturdier than the original steps. Very happy with the quality and service I received from


Fits great, like the holes for drainage


Great service. These are exact replacements for the steps on my Rockwood 8310ss travel trailer. My original steps caught the end of a high curb while entering a campground and no longer opened. It took three days from ordering to ups placing the new steps infront of my garage. The steps were exactly as described and will only require bolting onto the existing brackets.


This product was delivered on time and I was impressed with the quality. I needed to make a small adjustment to my existing bracket to account for the slide bar that sticks out each side of the stairs, but the bolt holes and everything else lined up perfectly.


The whole process and product are a 5 star rating. Ordering was easy and shipping on time. The steps are sturdy. Great down and out angle and I like the 9" width which makes getting in and out of the RV easy.



No problems..still an excellent product


etrailer delivered as stated on my replacement stairs. Not only did they show up in time, they were $50.00 cheaper than a RV store 5 miles from my house-including shipping. etrailer is the first place I will look for parts and accessories for my 2015 Sportsman.


Service was prompt and quick. My steps were delivered yesterday and I installed them this morning.

Bob B.


Steps have worked great during the past year, especially since I am taking care now when backing my trailer up.


Replaced the step on my camper with this one. Went from 2 step to 3. These did not mount up in the same holes as the old ones but a little drilling and welding and they are on. Work great, strong with non skid strips on front edge of steps. 3 step is much better than the old 2 step. Happy with this purchase. Shipped quickly.


We ordered these Flexco RV steps as a replacement after a minor accident that ruined the original steps. Our order arrived much sooner than expected, which was excellent as it was quite dangerous using the old ones. These steps actually seem to make entry and exit of our RV easier; they don't seem quite as steep as the original steps. Would definitely order from again. Great service.


After smashing my steps against a parking lot light standard i ordered identical steps from etrailer. The steps, item # SMFP-3100, are priced right and the quality is acceptable. They operate as designed with little effort. We travel months at a time and use our steps frequently. I certainly would recommend this product to anyone.


Wow, ordered the product on Tuesday, October 25, at noon and received a confirmation email the order was received. At 5:30 that day, received an email and tracking number that the product had been shipped. Came home Thursday at 4:00 PM and there was the boxed product in perfect condition. None of the typical shipping damage. Opened the box to inspect the product and it is exactly as ordered. Looking forward to installing on the trailer today. Thanks for the great service.


Customer service was great they help me find out the size I needed. Shipping was free and arrived on time. The step fit on the trailer with out a problem and worked as advertised. Thanks for all your help.

  • Would Triple Step SMFP-3100 Fit a 2014 Wildwood X-Lite
    I pulled up pictures of your 2014 Wildwood X-Lite and it looks like it normally comes with a double step. The Triple Step part # SMFP-3100 would work if you are looking for an additional step to make getting into the trailer easier. This step is designed to fit the mounting brackets of nearly all fifth wheel trailers but in a worst case scenario you would have to move the mounting brackets.

    A bad motor in your Lippert Coach step could be causing the gears to strip out. Most likely that is the problem. For a replacement motor you would want the part # LC301695. If you have a single or double step the correct replacement gear is the part # LC301696. .

    I do have a few options for you to consider however, we currently do not have a 3 step pull-out staircase with 24" wide steps for mounting brackets 25-1/2" wide. The correct way to measure the mounting brackets for your steps would involve recording the length from the center of each bolt hole on the brackets attached to the frame.

  • Can 2 Step of 2017 Forest River Work and Play 25WB be Replaced by 3 Step
    Going from a 2 step to a 3 step on an RV is definitely possible, but the mounting brackets are wider when going to the larger steps so you'd need the outriggers part # LC301704 to install a pull out 3 step Flexco like part # SMFP-3100.

This is a pretty common solution as long as the opening on your RV is wide enough to allow the added width to fit. It should be but it's worth checking.

    When changing the amount of steps you have on an RV like with the # SMFP-3100 it's pretty common that the widths of the brackets don't match up perfectly, but the good news is you can still install a different set as long as you are willing to make some modifications. What you can do is see if you can move the brackets you have now, weld the steps directly to the frame, or also you could go with new outriggers like part # LC301704 to replace what you have.
