Designed as a complete retractable entry step system for RVs, this Suburban TRIO 3-step unit provides a built-in staircase that folds and stores against the coach when not in use. Built for narrower RV door openings, it delivers a stable climbing surface that deploys outward from the frame to create full-height access to the entry door. A lift-assist hinge mechanism helps control the weight of the assembly during deployment and retraction, reducing strain when setting the steps up or putting them away. Once extended, the three-step layout creates a gradual rise for easier boarding, while integrated leveling legs help keep the system steady on uneven ground. Composite tread panels add traction and allow debris and water to pass through, helping maintain a cleaner and more secure step surface during use.
