Features to know about

Easier Entry Without the Wobble: 3" Drop/Rise with 21" Wide Step

A small change can make a big difference when stepping in and out every day. This single pull-out step gives a comfortable 3" drop/rise, making it easier on your knees and safer for your footing. The 21" wide x 8" deep step feels solid underfoot, even when carrying gear. It’s built from strong, rust-resistant black powder coated steel and rated for 300 lbs, so it stays stable and confidence-inspiring through years of use.

Sure Footing in All Conditions: Non-Slip Surface with Grip Tape

Slippery steps are a common cause of stumbles, especially in wet weather. This step’s non-slip surface with oval tread holes helps water drain and keeps your shoes planted. A 1-1/2" wide strip of grip tape along the front edge adds extra traction right where you step first, giving peace of mind for kids, pets, and anyone climbing in after rain or mud.

Tucks Away Cleanly: Low-Profile Design for Better Ground Clearance

No one likes steps dragging or catching on curbs. The Flexco manual pull-out design slides smoothly into its mounting base and locks securely in place for travel. When stowed, the assembly sits just 4-1/2" tall, keeping a low profile and preserving valuable ground clearance. It stays tucked out of the way until you need it again.

Built to Last: Durable Steel Construction and Simple Maintenance

The black powder coated steel frame resists rust and road wear, making this step both tough and easy to keep looking good. The simple manual pull-out mechanism means no motors or wiring to maintain—just slide it out when needed and push it back in when you’re done. With its straightforward design and 1-year warranty, this step is a practical, long-term upgrade for safer, easier entry.

Solid step - had to go with this model due to door position / frame configuration of trailer. Pleased with results though would have preferred two steps - had to use something with minimal drop for top step and two step units all had 6-7” drop to top step.

Single step actually working much better than expected. Inherent of step plus added distance from trailer floor due to trailer frame put the step mid way between the trailer floor and the ground.

by:
There is no complaints about this product! It was a great addition to my 6x12 enclosed work trailer's side door, and frankly, this should be a standard feature on any trailer like this. I never have a problem with this product "walking" its way to the extended position. The step always stays in place, retracted, until ready for use. It is never difficult to pull out or push back into place. And worst case, should I forget to push it back to the stowed position prior to getting on the road, the step does not stick out further than the tire, nor does the product hang down low enough to be a risk of catching on something and being torn off accidentally.
My reason for purchasing this product is that I stepped out of my trailer's side door one day onto uneven ground and rolled my ankle! Was down for about a month! Some people suggested a stool to keep in the trailer for this purpose. However, a stool sitting on uneven ground could still be just as dangerous as without it at all! So buy and install the step!
Installation of this step was fairly easy. One could opt to weld it to the frame of the trailer, but I chose to bolt mine. Depending on the frame configuration of your trailer, you may need an additional piece of steel, like angle iron, to install Be sure to used a locking type nut such as a nylock nut, not just or only lock washers. The outside frame of my trailer is a steel box beam, so you do not want to overtighten any bolts ran through this box beam. You can crush these beams! Again, another reason to use a locking type nut. See attached pics for further understanding of my description above, and for ideas for your own installation of this product.

Bought this for my enclosed work trailer to place under my curbside entry door. I LOVE it! Easy to install, solid construction, looks great. I had a single 16" step up into and out of trailer, with this step I now have two 8" steps which when you are carrying heavy items out of the trailer all day long, it makes it so easy and probably saved me from twisting my ankles and abusing my knees on a daily basis. Worth every penny! Loved it so much a placed a larger/wider pull-out step at the rear double barn doors of the trailer, that was a little more work to install, but again worth every penny! If you don't want a ramp door at the rear of the trailer, adding a step is the perfect solution.
by:
The steps came as described and were a great fit for my '89 Jayco pop up. Easy to pull out and they lock in tight for travel. I drilled 3/8" holes in my frame and installation was easy with 3/8" bolts. Sturdy and economical also.
by:
Perfect! Just what we needed for the small (12 ft) vintage camper we're remodeling.

Camper still in the renovation stage. Step is still just perfect!

My Coachmen Freelander Camper didn't have a step when purchased 11 years ago. I was much younger and never had a problem stepping up into the camper.Well now I have trouble until I found this step.Easy to install and plenty strong.Now I have no trouble getting in or out. Hard to believe 3'' makes such a difference.

Still going strong.Supports my 225 lbs. A very sturdy step.

by:
I ordered this step for my Jayco popup camper, knowing, based on my own measurements, that it would have to be drilled for installation. I had searched every trailer step that Google could find and could not find a better fit, and their price was the most competitive, even after adding the cost of standard shipping. I expected about a week to receive it but the eTrailer customer service rep took it upon himself to expedite the order in house and it arrived at my door on the third business day.

The step both looks better and feels more stable than the oem step did when it was new. eTrailer delivers quality product quickly and is my go to resource for trailer parts.
by:
I used them on my Ford F-250 utility bed. Mounted under bins to pull out to reach thing in bed of box
by:
Item was as described during ordering. Shipped and delivered promptly. I ordered this to install as a step for the rear of a trailer that was challenging to step up on.
the fit was perfect, installation was a snap and it is made in the good ole USA.
by:
Etrailer.com shipped it very quickly, and it was a perfect replacement for the steps on my pop-up trailer. Thank you for putting the hole dimensions on the website picture, it really helped me make sure it would fit my camper. Thanks again...
by:
Product is sturdy and should work fine. Box came with only one piece of tape on end, like it had been opened and re-closed. No instructions or any product details, warranty, etc. nor any hardware (i.e. bolts, washers, nuts). not sure if any were intended, but definitely would be a nice to have.
by:
Product is good quality. Due to the age of my camper the bolt holes do not line up so we will have to spot weld it in place as the add mentioned. no problem. quick shipping...
by:
The etrailer experience is great. I have always had good luck with them, and their prices are usually the best. I ordered on Wednesday, and my order arrived on Friday! Amazing.

Oh, and the step itself is VERY high quality, made in USA, works great. I will be installing it on our camping van.
by:
We received this product yesterday. We have not had time to open the package and preview the product. It was easy to order and we look forward to a product that will serve us for many years.
by:
Rebuilding an old rv trailer into a storage trailer. This fit just right and though it doesn't go down much it works.
by:
As described. The dimensions given on etrailer .com were very helpful in determining which step to purchase and they were accurate.
by:
It showed up and is the correct part.
by:
I bought these steps for our job trailers THAT THEY WORK GREAT
by:
The people at etrailer are always most helpful and deliver in a timely manner.
by:
The item arrived in good order.
However, the traveling box containing my product was previously opened, and the one-step product was not wrap in plastic bag - which I had expected.
Overall, I am really excited to have this product, which will improve the
entry-excite operation into my food trailer.
by:
My husband bought this step for his enclosed race car trailer and he couldn't be more pleased. It was exactly what he was looking for and needed. Thank you!
by:
Fast shipping and solved my problem. Catalog was easy to use and price and quality were excellent as well.
by:
Got it within a week. No more portable steps taking up space. Yea team!

  • Will Flexco Manual Pull-Out Step for RVs Fit 2019 Chevy Express 2500 Cargo Van
    Hi Mark; the Flexco Manual Pull-Out Step for RVs # SMFP-1220 isn't designed for your cargo van but I suppose it is possible it could fit without drilling. What you need to do is look underneath to see if the mounting holes line up. The front to back measurement between mounting holes on center is 12-1/2" and across the step on center is 22-1/2". There is a little bit of flex room in there since the holes are 1" long. If this doesn't match up under your van you would have to drill to mount...

  • Can RV Steps be Installed on 2020 Nissan NV2500
    Hey Terry, so we have RV steps that could possibly fit your 2020 Nissan NV 2500 like you are wanting but we don't have anything that is custom fit for your vehicle. That said, I am not totally sure what steps you are looking at but we do have the Lippert Outriggers part # LC301704 which you can use to attach Lippert RV steps in an area that doesn't have mounting brackets. Let me know which steps you are considering and I'll see if they would work.

  • Determining The Best Replacement Steps And Spare Tire Carrier For A 2013 Rockwood Premier 2516G
    Replacing pull-out steps won't require a bunch of modifications if we can find a matching fit to your current steps. To find the correct fit we'll need to know the entry height (measurement from the ground up to the mounting bracket) and the bracket width (horizontal spacing for the mounting brackets). The Flexco Manual Pull-Out Step for RVs # SMFP-1220 you were looking at has an entry height range of 10-1/2" - 13-1/2" and mounting bracket width of 24-1/4" wide. If you can get me these...

  • Recommended Installation Hardware for the Flexco Manual Pull Out Step
    The Flexco Manual Pull-Out Step for RVs # SMFP-1220 measures 21" wide, I double checked with the manufacturer on this as well. The distance between the center of the mounting holes is 22 1/2" , and since bolts aren't included you can use the Mounting Hardware for Lippert Electric and Manual RV Steps # LC118155-72 for install hardware.

  • Solution for Power Step Replacement on RV When One More Step is Needed
    I wish we had a step you could attach to the bottom step of your power steps but that's not something we carry. You would need to look into replacing your entire unit with a power step that has an additional step. I attached a link to a page that has all of the powered RV steps we offer.

    For your 2015 Minne Winne 31K, I recommend the Brophy Camper Scissor Steps - 2 Steps - Aluminum - Diamond Tread - 18" Wide - 250 lbs # AS02. These steps make it easy to remove when not in use and keep all your ground clearance for driving. Another option is to use the Safety Step Adjustable Height, Folding Platform Step - Aluminum - 24" x 16" - 1,000 lbs # SASXLA-09C-G which gives you adjustability for uneven ground and foldable legs. The legs collapse for a storage height of 4 inches....
