Is this right for you? Product Expert Kathleen M says:

Yes, if you:

  • Camp in areas with lots of gravel or sand that you don't want to track into your RV
  • Have a trailer or vehicle that you struggle to get in and out of and need to add a straightforward step to bridge the gap
  • Have an entry height (distance from the ground to the mounting point) of 14-1/2" - 17-1/2" and a mounting place that's at least 21" x 12"

No, if you:

  • Have a hard time with bending over and pulling out steps, and would rather have an electric step
  • Get annoyed when you have to supply your own hardware and want everything you need in the box
  • Have limited space behind where the step will mount - the brackets that the step moves on can get hung up
This 9" deep, pull-out step lets you safely enter and exit your RV. Slip-resistant step slides effortlessly into its mounting base and locks into place for travel. Bolts or welds onto your RV. Black powder coated steel is rust resistant. Great Prices for the best rv and camper steps from Stromberg Carlson.

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 21-1/16" wide and 6" 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

As advertised and excellent communications with
You can't go wrong!


Exactly what I needed for the restoration of my vintage 1972 RevCon. I looked everywhere for the proper dimension for the replacement step. These do the job exactly as expected. Minus one star because surface rust has appeared in the joints after 2 years (in California. so not extreme weather).


Fits and works great. Easy install


Good construction. Using it for side entry on a construction. Permanently in the pulled out position. The frame design of the trailer made this necessary but the step has adequate ground clearance to permit this. With regard to etrailer service, second to none.


Good product, sturdy, convenient, and decently priced. Installed it in about 1 hour.

Still working good, I wish I would’ve bought the 4 step unit instead of the 3 step.
Robert P - 06/10/2019


The step is attached .
Just needing to
tighten the bolts after reconstructing the entrance.


Tried to use this on an enclosed trailer I converted to a toy hauler. Due to trailer frame support placements, the step had to be slightly off center from door, but tried it anyway. Only had it on a few weeks before removing it and paint had already begun to wear off and flake off in chunks and some light rust already started. I can’t recommend this item since it’d clearly be a rusted mess within a year or two.
I now use an aluminum step platform with adjustable legs.


I love the flexco manual pullout step! It is exactly what I needed for my service truck. I have a large service truck that I work out of everyday and did not include any steps to climb into the bed. I recommend this step assembly for RV and obviously other use. Great product. Thank you!


Steps were installed by me-They were put on my Ford F-150 to aid my wife in getting in and out of the truck. (We are both now in our early 80's)

The steps work just fine. The only criticism I have about them is that they rattle a lot. I have added rubber strips in several places, but they keep falling off and the steps continue to rattle. Oh well, can't have everything, I guess.


Can always count on etrailer they have quality products at a good price.I restore vintage campers and for what I need they have never let me down, need to order from then again as soon as I get to that part of my winter restoration part of the camper. They are also very helpful in getting me and you the right product for what I need

Everything Ive ever Oder from has been great has always worked and is still working great thanks a lot
Dave S - 09/14/2016


Not my first time with etrailer. My product was described well, shipped fast and definitely a quality product. The price was very good also. etrailer is on my favorites list!

All is well and it has done the job for us.
James - 05/05/2016


Perfect, easy installation, we installed 2 on our shuttle bus (Chevy Express) so it would be easier for customers to enter and exit. highly recommend these steps based on cost, fast availability , ease of installation and performance

Excellent, no issues at all, still highly recommend.
Jeff - 02/12/2020


I damaged my original steps on our camper. I ordered these to replace. Removed the four bolts, put in the new set of steps that fit perfectly, reinstalled the bolts...BAM....done!!!


The step is just perfect for my box trailer. It actually a safety device to prevent accidents. Excellent metal work and a child could operate it. Packaging and shipping was heads above the other stores.


Used the step for passenger side step to get into pickup truck. worked fine for the wife.


Solid step. Easy to mount. Just what I needed for my 1977 Terry Taurus. Travel Trailer. etrailer has been a reliable retailer.


Easy to install


Steve, first let me start by thanking you for all your help, specially for doing the research for the right fit for my trailer.
The step was a perfect fit. The step is of good quality material. I am sure we will enjoy it for a long time.

Once again thank you Steve for all the assistance.



Every item I purchase from is of the best quality. They are also very good with working with you to find your proper item. If you purchase an item that does not work out for you, they happily let you return it. Very nice company to deal with.


This is a very serviceable product. Thin metal but equivalent to standard issue steps. Fit perfectly and works smoothly. Very good price and shipping was quicker than expected!


My confidence in the way companies treat customers lately was low until You guys rock!


Just what I needed to give a boost to my too high step
On my horse trailer.


I use this step for my 2016 Promaster 1500 van . Makes life easier entering & exiting the back of the van. 100% satisfied !!


Superior product and price was great!! Fast shipping too. Will continue to shop with


Fit perfect, 350lb weight limit makes it rock solid.

  • Depth of Flexco Manual Pull-Out Step Single SMFP-1120
    The stored depth of this step from the center of the front mounting hole to the back of the slide bracket measures 11 inches. The height of the step will be 7 inches when it is stored. I have attached diagrams showing these measurements. To make sure this step will work for you, you will want to make sure that you have at least 11 inches behind the mounting location of the front bolt hole to install this step. As long as you have the 11 inches behind the front bolt hole, this step should...

  • Can the Flexco Manual Pull-Out Step SMFP-1120 Attach Using Sides of Mounting Bracket
    If the brackets on your camper match up to the side holes of the # SMFP-1120 it would work just fine to use them. Nearly all RV steps like this attach with the side holes and not the holes on top. If the install brackets on your trailer are right at 21 inches apart this step would fit perfectly as that is the outside overall diameter of the steps.

  • Could Flexco Pull Out Step Replace Kwikee 28 Series Step
    If the brackets on your camper match up to the side holes of the # SMFP-1120 it would work just fine to use them. Nearly all RV steps like this attach with the side holes and not the holes on top. If the install brackets on your trailer are right at 21 inches apart this step would fit perfectly as that is the outside overall diameter of the steps. If the dimension is slightly different a fabricator could easily move the brackets to get the steps to fit properly.

  • Availability of Replacement Single Step with Mounting Frame Brackets 22 Wide
    The closest we have to a 22" mounting bracket spacing is the Flexco Manual Pull-Out Step # SMFP-1120 which has mounting bracket that are 21-1/16" wide. If this doesn't fit (which it sounds like it won't) then I recommend going with the Flexco Manual Pull-Out Step # SMFP-1200 and using the Outriggers # LC301704 to replace your current mounting brackets. These will enable you to get the desired mounting bracket distance.

  • Alternative Entry Steps for 2017 R-Pod 179
    The R-Pod 179 usually comes with a single-step pull-out stair unit like either 24-inch-wide Flexco # SMFP-1200 or the 20-inch # SMFP-1120. Both are single step assemblies but they differ in the amount of drop/rise. You may have enough ground clearance to install a different step, one that either has 2-steps to reduce the height of each step up, or one that has a better step height. You just want to ensure you do not reduce the trailer's ground clearance by installing a step assembly that...

  • Installation of Flexco Manual Steps When Mounting Hole Dimensions Dont Line Up With Previous Steps
    The Flexco Manual Pull-Out Step for RVs like # SMFP-1120 and most other brands as well use outriggers like # LC301704 to mount when the mounting holes of the original steps are not a perfect match. The outriggers are able to be mounted wherever needed to support the steps. They use hardware like # LC118155-72 for mounting to the outriggers.
