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 25" wide and 12-1/4" 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.

Exact replacement for Kwikee series 39 Electric step.
I had ordered one from a competitor before ordering from etrailer.com.when it arrived it was wrong step (not even close) Fast shipping!
I ordered on a Monday and received on Thursday. It took longer to remove old step than to install the new one .
Make sure you have replacement mounting bolts incase the old ones break. 3 out of 4 of mine broke.

  • Can Kwikee Series 39 RV Powered Entry Step Replace a Series 26
    According to the Kwikee Step folks at Lippert, the # LC3724742 Series 39 step will indeed work with your current wiring and will bolt up just like your current set of steps.

  • Recommended 2 Step Powered Step Unit to Replace Kwikee 28 Series Step on Travel Trailer
    According to Lippert, the closest they can get to the 22 inch by 6-1/2 inch bolt pattern of your existing step would be the # LC372261 Kwikee 32 series, which has a 22 by 8 inch bolt pattern. Although you'd need to drill a couple of holes, the Series 32 would be your best bet as they don't have a 2 step option that would match up exactly to your existing bolt holes..
