With the Lippert SolidStep RV Entry Step System, you can get in and out of your rig with more stability, safety, and ease. Engineered to make your life on the road safe, convenient, and simple, the SolidStep is the upgrade your RV needs before your next big trip. Stop unfolding manual steps or worrying about wobbly steps that aren't stabilized securely on the ground. Whether your camper is parked on pavement or on uneven terrain out in the woods, the SolidStep's leg extensions adjust individually so your steps can adapt to any surface. Plus the recessed feet at the bottom of the step help to prevent tripping hazards and allow for maximum clearance for your camping spot. When you're ready to move on to the next adventure, all you have to do is fold your steps right up into your entry doorway where they securely lock into place until you're ready to use them again.
