Kwikee 3747453 Short Term

Kwikee electric RV entry steps provide an effortless, convenient way to enter and exit your RV. The steps are wired to your RV's door and feature an automatic extension, unfolding when the door opens and retracting when it closes. This differentiates the steps from the alternate manual pull-out steps.


Motor, Gearbox, Linkage, Control Unit, and Switch Kit

The updated Kwikee steps manufactured since 1999 require the integrated motor, gearbox, and linkage (IMGL) setup to power the steps. The motor provides the power, the gearbox turns the linkage arm, and the linkage pushes the steps out and pulls them back in when rotated by the gearbox.


The motor powers the control unit, which senses when the RV door opens and closes, extending and retracting the steps in tandem. The switch kit - consisting of 2 magnetic sensor pieces that mount to the door and doorframe, and 1 rocker switch - works with the control unit. When the sensor pieces come into contact with each other, the steps are pushed in or pulled out. You can override the automatic retraction with the rocker switch. This will lock the steps in the extended position.


The included 4-way plug fits into the existing wiring harness on your RV. Most vehicles should having this wiring already set up. In the event that your RV is missing the wiring, a 4-way pigtail is included to help you hardwire the unit to your RV.


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 24-1/4" wide and 8-9/16" 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 24-1/2" wide to 36-3/4" 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.

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. 811628

Upon opening the box, I bench tested the 28 series steps and they worked perfectly. Once the older steps were removed, the installation went easily. I used a floor jack to lift and hold the 28 series steps in place thus allowing me to Mount them alone. 893284

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. 892119

Review from a similar Kwikee 28 Series in RV and Camper Steps


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. 819300
