Is this right For you? Product Expert Kathleen M says:

Yes, if you:

  • Have an entry height (distance from the ground to the mounting point) of about 23" - 26" and a mounting place of least 24-1/4" by 14-5/8"

No, if you:

  • Need a whole setup for your steps to make sure that everything is fresh and new
  • Have a bad back, knees, or hips and need steps that make solid contact with the ground to eliminate the bouncy, diving board feeling

Note: This step assembly includes the steps, motor, and switch kit only. The steps will operate manually through the switch kit.

If you want the complete step assembly that allows the steps to automatically extend and retract with the RV door, you will need a control unit. The switch kit included with this assembly will still work, but if you want to be able to override the automatic retraction, so the steps stay out whether the door is open or closed, you will need a different switch kit. The complete assembly with steps, motor, control unit, and switch kit is available under part number LC3726892.

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 25-7/8" wide and 14-5/8" deep.

If it turns out you have more or less space beneath your doorway, there are other step assemblies available with bracket sizes available 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.

  • Recommended Heavy Duty Replacement for Kwikee Series Steps
    If weight capacity is the primary concern then you will want to take a look at the SolidStep Manual Fold-Down Steps as there is not a heavy duty version of the Kwikee Series Steps.

This will be the best replacement for your Kwikee Series as they install in an odd fashion that most other manufacturers do not make replacements for.

  • Troubleshooting Powered Steps on a 2008 Holiday Rambler that will Not Fully Extend or Retract
    We don't carry the SCS/Frigette brand of steps so it's a little hard for me to troubleshoot the problem you are experiencing, but it sounds like the gears of the steps are jamming up which is preventing the steps from moving more than just a little bit. What I would recommend you do is get underneath it and inspect the gear assemblies to be sure there isn't anything stuck in the gears or that the gears themselves have been damaged. You might also check the condition of the wiring. A bad...
