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 camper 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 34" - 37" and a mounting place that's at least 28" x 12"

No, if you:

  • Have bad knees, back, or hips and want to avoid the diving board effect from this style of step
  • Get annoyed when you have to supply your own hardware and want everything you need in the box
  • Hate feeling the whole camper rock when anyone goes in or out, and prefer steps that make contact with the ground
These 9" deep, pull-out steps let you safely enter and exit your RV. Slip-resistant steps slide effortlessly into their mounting base and lock into place for travel. Bolt or weld onto your RV.

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

These 9" deep, pull-out steps let you safely enter and exit your RV. Slip-resistant steps slide effortlessly into their mounting base and lock into place for travel. Bolt or weld onto your RV. Black powder coated steel is rust resistant.


I had my new 4 step for just over a year now. They still work and look great. What a difference they have made on getting into and out of the camper. The step from a 3 step to a four step is much better on the old legs . I wish I had gotten these sooner. Just a small amount of rust showing in a few spots but some spray paint will take care of that soon. Will buy again if and when these need replacing.


We love these steps. We has three steps before and adding one step puts less stress in my knees.


We installed these steps as replacement for the original which was damaged. They work just fine and are even better looking and with better non-slip surface. We are very pleased with them.

Great! Love them even more. They feel very safe and solid compared to the original.
Karen Y - 09/18/2021


I received the ordered stairs and they arrived a few days later. Due to weather, I haven't gotten them installed as yet but my wife (a Shortie) is looking forward the the 4 entrance steps instead of the original 3 steps. (A couple of years ago I 'reversed the axles on the trailer which increase the entrance step height about 5" from the ground.) Hopefully she will be a 'Happy Camper' now that she can enter the trailer easier via the new 4 step installation. Thanks Etrailer for another great product! I may have rated the steps to 5 stairs if I already had the steps installed?


Ordered these steps and 3 days later delivered to my front door. About 3/16" wider than the original Flexco triple steps I replaced on my Cedar Creek fifthwheel, but still fit. I did have to trim about 1.25" off the bottom of the existing mounting brackets under the entry door that these steps bolt on to, but not a big issue. Good sturdy steps.


Great step has made it easier to get in the trailer. I don't understand why they don't put four step on trailers when new. Arrived on time easy to install in 30 minutes with help of a floor jack.


No hassle ordering and products came fast. Just finished putting my new flexco quad steps in. Excilent products. Best pricing i could find and with free shipping it's a no brainer.


Looks like a great product, if you ignore the box it came in. I received the steps in a badly beaten box with many holes. The holes were where the edges of the steps broke the box sides. Cardboard not thick enough to prevent this problem. Good thing no mounting hardware was included, as it would have been lost in transit. I was warned by a friend of mine that received their steps the same way. I haven't mounted steps yet, but looks like they will mount very easy. I'm replacing a 3 step with this 4 step, because the bottom step on the 3 step is 12" off the ground.


Great service from your staff. Haven't unpacked the steps yet and plan to imnstall them tomorrow.

Great. Better having less rise in each step.
Donald - 01/12/2020


I bought these steps a year ago,they work very well,an bolted right up to existing bolt holes!! They fold in an out very easily,my wife has no problem folding them in an out. I would recommend them if you need the additional step.


We have ordered from etrailer previously and always had great results. Same this time. Product was exactly as presented, shipping quick, and price was great!


I needed replacement rv steps. Product was easy to order and was delivered promptly. Good value.


The four step stairs are great. Minor cutting with a saws all to clear the top stair slide out. The fitment was perfect and the quality of the product is great. Would recommend these steps to others


Details on web site not as clear about measurements.but with LIsa help got what I needed to know. Steps fit like they should. Thanks


We were able to remove and install the new ones in an hour..we couldn't be happier having the extra step. With an elderly dog it makes things easier for him. Adding the carpet wraps were a bonus.


Great product.Installation was simple.Madison H and etrailer were great to work with.


Installation required some modification for replacing a three step version. The steps themselves required some modification to make them level. A few of the welds were not very good quality.


Always great products at etrailer. I don't even look elsewhere any more.


Got it today as promised. Installed it in about an hour. Works great. My wife is disabled and was haveing a hard time with the 9" rise on the steps. She gets up and down much better with these.


Removal old of three steps and installing new steps was no problem wonderful having the four steps to use


Very pleased with stairs
Was a perfect
fit for the ones I destroyed
Price was great and shipping was free
Had them in 5 days
Will use
etailer again

very well fit was good
david b - 09/10/2018


Outstanding service. Actually was able to talk to a human, not a machine. How unique is that. Great service and fast shipping.


They've continued to work flawlessly on our campground's hayrack.


The step was delivered as expected in great shape. looks great.
The square hole the old step was in, is not square and this one takes up all of the room. trying to fix that.

Thank you. A job well done.


Product was a name brand exact fit as represented. Stronger than original. Totally satisfied with the purchase.

  • Replacement 3-Step Manual RV Steps with 4-Step Manual RV Steps
    Manual RV steps # SMFP-4400 could work for you. This is a 4-step unit that is 28-1/8 inches wide overall and 12 inches deep (front to back) and 18-1/2 inches tall. None of the other 4-step options are as close in the measurements of what you have now. the 4-step model will hang down at least 4 inches more than the 3-step model when the steps are extended.

  • 4-Step Manual Pull Out Steps Less than 16-3/4 Inches Tall When Retracted
    Yes, you could use it and it is 18-1/2 inches tall so it would hang down 1-3/4 inches more than your existing steps (since it has 4 steps and yours currently has just 3 steps). Please note that RVs and trailers are built with a specific set of steps based on the design of the vehicle/trailer and often times going to a different set of steps will not work.

    You are correct. the RV steps we offer are 24-inches wide regardless of the amount of steps. I recommend installing replacement steps like part # SMFP-4400. These are 24 inch wide steps. The mounting base dimensions are 27 inches wide x 9-inches deep. You would need to build up the mounting location on your RV to work with these steps.

  • 4-Step Pull Out Recommendation for 2010 Cougar 5th Wheel by Keystone
    Your 2010 Cougar by Keystone has a Lippert frame so that means that our RV pull out steps like the Flexco Pullout 4-Step part # SMFP-4400 are going to bolt right up since these steps are designed to attach to the Lippert mounting brackets. These are overall 28-1/2 inches wide so you can also compare that to the mounting brackets of your trailer to see if they are a match.

    For your Cedar Creek 36ckts 5th wheel trailer, I recommend the Flexco Manual Pull-Out Steps for RVs - Quad - 8" Drop/Rise - 24" Wide - 300 lbs # SMFP-4400. I have attached pictures of the dimensions of these steps for you to determine if this will be a good fit for your needs. This will give you a little over a 27-1/2 inch drop from your frame when fully extended. You will want to make sure you have enough ground clearance to add that additional step.

  • Will Flexco Manual Pull-Out Steps Fit in Place of Hickory Springs Steps
    Going from a 3 step to a 4 step is going to reduce the ground clearance and that could end up being an issue depending on the terrain. The difference is width would seem to be off just enough to where you would not be able to mount the new steps in exactly the same holes as the old steps. Not that drilling new holes is all that difficult but if the more narrow span does not line up with structural metal to handle the weight then it isn't going to work.
