This setup replaces the step, motor, and control unit for the Kwikee 28 Series, so it automatically extends when you open the door and retracts when you close it. The 12V motor and control are wired through a 4-way plug, with a 10A control unit and 12 AWG/16 AWG wiring for reliable performance. You don’t have to think about switching it on or off—it just works every time you use the door.
The powder coated steel frame and solid drive rods with stainless steel bushings make this step strong and smooth. The 23-5/8" wide by 10-1/2" deep tread has a non-slip surface and reflective strips for visibility. With a 300 lb weight capacity, it stays steady when you’re carrying gear or helping someone climb in, and the 7-1/2" drop/rise makes the step up or down feel natural.
You don’t have to worry about the steps getting damaged or left out while driving. The motor automatically retracts if it hits an obstacle and also pulls the step in when the ignition is turned on. These features protect the step and prevent accidental damage if you forget to stow it before moving.
The mounting plate measures 24-1/4" wide by 8-5/8" deep with a 22" x 6-1/2" bolt pattern, so it fits securely in the existing space. The step extends to 9-5/8" and folds to just 6" high, giving you good clearance when retracted. An amber C193 incandescent light automatically illuminates the step so you can see where you’re stepping at night.
Every connection and pivot point is built for long-term use. The weatherproof wiring resists moisture and road grime, and air-pressed rivets at each pivot keep the mechanism tight and stable through years of movement. It’s a single-step design that’s simple, strong, and ready to handle daily use for RV life or travel.

I was told 2 to 3 day shipping I ordered it on Friday it sat in their warehouse on Friday night all day Saturday all day Sunday final shipped on Monday received on Wednesday had to leave for vacation on Wednesday morning so no working step on motorhome. Very disappointed with shipping service. Other then that they send great instruction videos
This was a like for like replacement for a ten year old one. The rivets which hold the step to the frame, wear over time, allowing a little slack between the two and a rattle underway. It always operated correctly.
Product works great, but the best part of my experience was the how to video on your site. Watched the installation video with the best tips on installation and the change out was accomplished in less than an hour. Thanks for adding that value to the product. Well done.
First off shipping was fast. Recieved the step in 3 or 4 days rather than the estimated 12 days. Fit the original like a glove. Remove 4 bolts, replace, plug it in and back in business. Works great. The short YouTube video showing how to extend the step for easier installation was very helpful. Thanks etrailer.
Good price... delivered promptly...what more can one ask for. Kwikee steps well not so happy with them...I’m on my 3rd one in 3 years... although one was impacted by a large piece of asphalt on the road. Seal the wires going into controller will prevent moisture entering it... one failed due to that.
Received my Kwikee Motorhome step today. It was replacing my 17 year old step that I had been having intermittent problems with recently.
It was a perfect replacement, plug and play, and I expect it will last me another 17 years.
Thanks etrailer!!

I've ordered from etrailer in the past and, like those orders, their products are all of great quality. These Kwikee steps are well-manufactured and working with etrailer was very pleasant. They fully honored their price guarantee. I couldn't be happier and will order from them again.
Purchased a replacement step for our 2 year old coach that was inoperative when we bought it slightly used. The original step was poorly maintained by the original owner and very erratic. The replacement was exactly as described, came with good instructions and has performed well this past year. Pricing from trailer was good and customer service excellent. Will shop them again when needed.
Great replacement for my 10 year old step. I had to order a new magnet switch because the new unit was working backwards. But now that the new switch for the newer units is in its perfect.
Everything that had to do with my purchase (customer support, delivery, product quality) was perfect. The only reason it did not get five stars is because there is no disclaimer that the motor in the steps have had their polarity reversed. in other words the steps will close when the door is opened, and open when the door is closed. There is a magnetic switch that also needs to be replaced, the new stitches are considered a Normally Open switch, some model motorhomes have Normally Closed switches installed at the factory just inside your screen door. They are simply a magnet that tells the control module wether the door is open or closed. Check before you order, etrailer carry them and are easy to install, just stinks having to pay shipping twice.
exactly what i needed to replaced a road damaged unit... this has a slightly smaller profile (6" vs 7")... easy to install... unit showed up in 4 days!
Thanks!
This step works great. I was very surprised that it worked for my rv. Thank you.
Customer service was very attentive to inquires, delivery and general satisfaction.I ordered a Kwikee replacement step assembly for my RV which seems to be of very good quality and am sure will fit perfectly.A great experience!
The steps arrived as expected. They are identical with the exception of the wire for the outdoor light. I have taken the old ones off but not put the new ones on. The person I spoke with was very helpful with the steps. Installation begins in the morning. I am only giving 4 stars due to the lack of instructions. I am having to find the links online. It could have made suggestions for making the project easier or something even though it appears to be quite simple.

Great, it is easy to hook up and we feel safe towing our jeep.
Fast shipping fantastic service great c ommunication
The support at etrailer is examplitory..excellent. They helped me correct my mistake ordering the wrong part and got the right part to me without any problems. Thank you.
Worked as expected. Arrived quickly. Happy with the service and product.
Step arrived promptly and damage free. Install was challenging as the bolts holding the old one on had rusted and prevented the nuts from coming off completely. My daughter and her beau make a good team, got it off and installed the new one without further issue. He even added some locking nuts for additional peace if mind.

That's awesome that your daughters beau was able to get everything installed an make it extra secured for you, Paul! Nothing beats some peace of mind when it comes to something like steps :)
Fitment was spot on and connections all lined up for my 2008 Fourwinds Siesta 29BG.
We replaced a damaged step a year ago. The new one from etrailer has performed great! We really like working with etrailer.
Steps look nice but they don't fit my RV Too short
Awesome step ! No more stool to fall off of !
etrailer shipped the step out fast !
Me and my wife just love it !
Thanks guy and gals at etrailer !
You have a customer for life !
Not fully installed yet, but is physically identical to the unit I am replacing
company cannot even afford 4 bolts for mounting. no installation instructions, no warranty card. minimum basic customer service is no existent
Customer service is great! They keep you informed the entire order of your order!
I was expecting the steps, the motor and the controller. After looking at the pictures, I spotted the arm assembly in the gearbox.
I called to verify if that was part of the price. It was! I didn’t have to use the gearbox and the arm assembly from my old steps!
Plug and play! Thanks etraialer
