MORryde StepAbove Gen 2 Add-A-Step Parts and Accessories Guide
The MORryde Add-A-Step creates an extra lower tread for compatible Gen 2 StepAbove RV stairs when the first step up from the ground is too high. Two sizes are available: 23½ inches wide (STP54-075) and 19½ inches wide (STP54-076).
The kit is designed to attach to a MORryde Gen 2 StepAbove assembly, including the compatible Strut Assist version. It adjusts for 8-inch and 9-inch rises and includes extended support legs to accommodate the added step.

| STP54-075 | Wide StepAbove | 23½ × 7 in | Shop STP54-075 |
| STP54-076 | Narrow StepAbove | 19½ × 7 in | Shop STP54-076 |
Measure the flat tread on your existing StepAbove assembly. The size refers to the width of the added tread, not the RV doorway. The added step is removable and uses the manufacturer's longer support legs for the change in height.

For the three- or four-step handrails, MORryde specifies 36 inches of interior doorway clearance. The Gen 2 handrail numbers differ from those for older StepAbove generations.
Before installation: Confirm the StepAbove generation, tread width, original mounting points and surrounding clearance. Use MORryde's Add-A-Step mounting procedure, including the longer legs and the prescribed adjustment for the actual step rise.
