Note: This step assembly includes the steps, motor, and control unit only. The steps will operate automatically, extending when the RV door opens and retracting when the door closes.

If you want the complete step assembly that also allows you to override the automatic retraction so the steps stay out whether the door is open or closed, you will need a switch kit (sold separately).

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 30-1/4" wide and 24-11/16" 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 24-3/4" 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.

Average Customer Rating:  4.6 out of 5 stars   (9 Customer Reviews)

Replaces the electric steps, motor, and control unit for your Kwikee 42 series RV steps. Motor and control unit automatically extend and retract the steps when you open and close your door. Wiring pigtail hardwires to your RV's power.


Was a perfect fit for my 2005 Holiday Rambler Navigator. Listing says 25 1/4” width but it’s really 26 1/4” which is the correct size for Monaco built RV’s. Stainless trim from original steps needs to be transferred. Also I needed to trim some fibreglass panel on the lower fender to free the old steps.


The step works great. It was an easy install for replacement.


Very glad they had this step and installation went well.


Excellent product. Reasonable price. Fast shipping.


This step was a perfect replacment/upgrade for my coach. The only issue I had is it got damaged during shipment and emailed had to send out another unit. This item should be shipped on a pallet to avoid damage both saving me time and etrailer money. I would order again if the need arose.


As advertised, works well! Thanks

  • Folding Handrail Recommendation for a Motorhome
    To add a handrail for use in conjunction with the Lippert 42 Series Steps # LC372779 we need a universal option as there aren't any made specifically for this step. The Stromberg-Carlson Folding Handrail # AC-544 has been a standard for years and is a solid choice to help make it easier to enter your motorhome. If you want to add some grips to it to make it a little easier to use then we have that available in 9" segments as part # AM-01.

  • Where Do I Need to Measure for Replacement Steps on My 2007 Western Alpine
    Sorry to be the bearer of bad news Jeffrey, but really the only way I am going to be able to get you situated is for you to measure. It hopefully won't be too bad for you since it's only a couple of quick measurements. You're first going to need to measure the width and depth of the space beneath your doorway, as well as the distance from mounting point to the ground. With these measurements I'll be bale to find you a set of steps more suitable for you.

  • Can Lippert SolidStep Be Used on a Class A Motorhome
    That's exactly why you need to use electric steps like what we see with the Kwikee Series 42 # LC372779 steps. Class A motorhomes just have that one entrance which would make it too difficult to utilize a pull down step like the Lippert SolidStep # LC791574. I you're needing to replace your electric steps then the 42 Series I mentioned above are a good fit if the entry height is 15-1/4" - 17-1/4" and the 29" wide x 18" deep bolt pattern matches.

But the powered 40 Series Kwikee Electric RV Step, # LC3726892 with a bolt pattern of 20-1/2" wide x 12-7/8" deep is the pattern the manufacturer set for their product; it is not an industry standard bolt pattern that is matched by others.

  • Troubleshooting RV Door Steps that Extend and Retract Backwards
    It sounds like you have a couple wires run backwards on your Lippert powered steps. Its hard to say exactly which wires are wrong but most likely a power wire and ground is backwards. The best recommendation I can give would be for you to go over the wiring and verify everything is connected correctly. The green wire gets grounded to the chassis. The white wire gets connected to the power switch which then goes to the positive battery post. The yellow wire gets run to the a keyed power...

  • Replacement For Kwikee Series 42 Steps
    Hi Rick; so unfortunately that is not correct due to the age of your Series 42 steps. Per Lippert (the manufacturer of Kwikee), steps from early 1999 actually have no replacement parts available due to the age (see below). So while I know it stinks, the only thing I can offer is to replace your Series 42 steps with a new unit, the Replacement Steps, Motor, and Control for Kwikee RV Electric Steps - 42 Series # LC372779.
