Safety Features

The Kwikee steps include several safety features in an effort to prevent injury to you or your passengers and damage to the RV steps. If an obstruction is detected while extending, the steps will halt and retract back into the stowed position. The steps will also retract when you turn on the vehicles ignition, even if the automatic retraction override has been activated, in case you forget to stow them before driving away.

Will Kwikee Electric Steps Work for You?

Electric steps are typically installed on RVs and some travel trailers. The electric steps from Kwikee 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.

Kwikee In and Out

The Kwikee electric 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 doorframe, and measure the width and depth. You will need a mounting space that is at least 24-3/4" wide and 8-5/8" 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 24-3/4" wide to 37-1/4" 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?

Kwikee Entry Height

To decide on 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 6" to 8" to account for the drop from the bottom step to the ground. This measurement will also tell you how many steps you need.

The chart below displays mounting bracket widths 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.

delivered on time. perfect replacement.


The Keikee Electric RV step from was a perfect fit for our Thor ACE motorhome. I would recommend for rv parts and automotive parts replacents.


This was the old step!
Took 2 hrs to
change out. It's plug and play!
Great product.


They were very helpful when I called looking for this step because I didn’t see exactly what I needed and they gave me step come right up


Bolted and Plugged right in on my 2001 Winnebago Spirit Motor home. No modification. Old step was a Kwikee 28 Series Single Step. Works just like new.


The step is a replacement for the old one that was on the motor home
The bolt holes to mount it were an exact match the wire diagram was a little different than the old unit
The unit works great and was a lesser price that some others I have looked at


It came very quickly.The box was damaged,but all appears ok. Going to install this weekend,if the weather permits.The one I'm changing out is a exact replacement. Thanks!


It came qiuck, haven't used it yet , will send photo when done


Bolted up onto existing bolts and wired exactly the same. Easy replacement.


Fantastic and personable service!


Well built. Would recommend keeping them lubricated at the pivot points with an aerosol grease. Obviously exposed to the road elements and it gets squeaky quick.


Ordered the kwikee 28 electric step for my class A Winnebago. Bent old steps up in construction zone in northern Colorado
The price was reasonable and the step arrived as scheduled. Was identical to old step and bolted right up. Tried to use the original door switch but step retreated when door was opened. Wired up the new door switch which was included...everything worked great. Step is still working great after 1 year of service with numerous trips---long and short. Retired and use the rv weekly. Very pleased with product and etrailer.


Ordered my Kwikee 28 Series Electric Step on line. Later that day I received notice they had processed my order and that it would be shipped and received in 5 days. Received it on the date they had listed and I installed it on our motorhome with the help of a friend. The installation directions were well detailed and it was installed and working in just a few hours. Now a Happy Camper. Thanks Will be sure to use your services as future needs arise.


Kwikee step is well made and easy to install. E-trailer customer service was the best! The step arrived by USPS in 4 days. The installation instructions were easy to read


Good price, fast delivery, no issues whatsoever. A quick replacement of the same model that came on my RV.


New electric steps arrived faster than anticipated. Perfect fit and as soon as I plugged in power cord, steps extended and retracted first time. Existing door switch worked too and all I had to do was zip tie wires and we were all set to go.


Purchased 1 year ago to replace a damaged unit on my motorhome. Installation was simple and after 1 year it still works perfectly. Great company and will always look to them when and if I need additional items.


As described. Everything in the box. Fast free shipping. Easy to follow instructions. Great replacement for my existing 16 year old motorhome step.




Witing wise it fit perfectly as replacement but the mounting holes would not line up so I have to drill them out a bit...otherwise it should be good fix for us


Everything was as advertised. The fit and installation went very smoothly. Thank you!


Our Steps came way earlier then expected ! What a surprise. Vicki was awesome to work with !. We are anxious to get them put on. Will update the outcome when we put them on.

Our box was a little beat up but everything seemed to be ok inside the box.


This was the exact replacement for the job.


Very professional service. Arrived speedily and was great fit. I will certainly keep their number handy for any further requirements for my motorhome. Thanks.


Perfect fit, easy install done in 30 minutes great replacement product
Tks Allison

  • Does Lippert Kwikee 28 Series Electric Step part # LC3747453 Come with Pigtail Connector
    The Lippert Kwikee 28 Series Electric Step part # LC3747453 does come with a pigtail style connector that you'd wire to your RV and then plug into the matching female connector underneath the step. I attached a picture of the connector for you to check out as well.

  • Replacement Controller for Kwikee Steps
    I reached out to Lippert and that number doesn't come back as anything. Typically it starts with an S. If you can find the tag and send a picture of it that is fine too. At the very least if you can tell me which series it is along with the year of your RV they can probably narrow it down to find the right one but the serial number is the easiest way to do it. The picture can be sent as an attachment in response to the email you received with the link for this answer page.

  • Will the Kwickee Series 28 Electric RV Work On A 2001 Class A Beaver RV?
    When choosing a replacement set of RV steps, the important measurements to consider are the dimensions of the step's housing that actually bolts to the RV. The # LC3747453 has mounting plate dimensions that measures 24-1/4" wide with a 22" wide x 6-1/2" deep bolt pattern, as shown in the provided photo. If the mounting location on your RV can accommodate the size of the housing, these steps would work great! The best way to determine fit is to measure the housing of your existing steps.

    Hi Ralph; it sounds like you're already aware of this but adding steps like the # LC372261 you were looking at would be a completely custom job. There is no real measurement for fitment so I would look at potential clearance issues and how far the steps will come down when extended to see if that will work. These particular steps have a height of 7-3/4" when folded and 14-1/8" when extended. The steps measure 23-3/4" wide x 11-3/8" deep with an 8" drop/rise. When we have come across this...
