yo, Thanks guys for getting this thread back to the top; I have been thinking about some info and finally found it deep inside my site;
Kodiak Sidewinder automatically lowers only when you open the door to help you step into or out of your vehicle, and then retracts once you close the door. That way, it does not clutter up your SUV or truck, allowing you to preserve its good looks. The Kodiak Sidewinder is so unobtrusive that you would not even notice it when your car doors are closed.
Aside from being easy on the eyes, the Kodiak Sidewinder is also very ergonomic. It lowers the regular step-in by about eight inches, so you never strain your knees as you get in and out. Note that the step is attached to your SUV or truck's rocker panel, so the extension may vary (but only very slightly) depending on your vehicle's model.
Please avoid cutting or lengthening the arms of the step to put it in trucks and SUVs with high lifts. Modifications like this are not backed by Kodiak and may nullify the warranty. If you need to modify your Sidewinder, there are 12-inch leg extensions and side winder kits available for vehicles with lifts.
Made to last, the Kodiak Sidewinder can hold up to 350 pounds, and features a non-skid tread so you never slip. The sure-footed unit also has a reflective strip so you see it even in low lighting conditions.
The Kodiak Sidewinder also comes with all the safety features necessary. Its electronic control immediately keeps the step from retracting or extending if it touches an obstacle.
Specifications and installation
The Kodiak Sidewinder is 5 inches by X 11 inches. You can choose between two colors,? black or silver-coated finish. If you have some level of experience working with power tools, you may be able to install Kodiak Sidewinder yourself. All you need to do are simple vehicle frame drilling and wiring. Authorized retailers like ElectricStep.Com offers free downloadable installation manuals in this website.
Maintenance
The Kodiak Sidewinder should last for years and years with proper maintenance. Instructions on how you can properly grease the bearings are also available at here at ElectricStep.Com - simply download them when you buy a Kodiak Sidewinder.

Try an RV store; aside from an electrically operated step, maybe spring-loaded that would pop back-up after you step off of it
