MORryde Strut Assist STP-205–214 Step Parts & Fit Chart

MORryde's StepAbove Gen 2 Strut Assist steps fold into the RV doorway for storage. Gas struts help lift and lower the staircase, while adjustable legs support it on the ground. There are four separate models; the correct one depends on the door opening and the height from the ground to the threshold.

The Strut Assist family has a 500 lb rated capacity. A standard Gen 2 StepAbove staircase does not have the same hinge and gas-strut mounting assembly, so use the strut-specific fit and installation drawings below.

StepAbove Strut Assist model and doorway chart

Use the width on the RV manufacturer's door label or measure the narrowest flange-to-flange opening at the base of the doorway. The 26-inch and 30-inch figures below refer to the factory door sizes, not the width of an individual aluminum tread.

MORryde MPN	Steps	Step height	Rise	Factory door label	Doorframe opening
STP-205	3	31½–37 in	9 in	26 in	23¾–24¼ in
STP-210	3	31½–37 in	9 in	30 in	27¾–28¼ in
STP-211	4	37½–42 in	8 in	26 in	23¾–24¼ in
STP-214	4	37½–42 in	8 in	30 in	27¾–28¼ in

STP-205 and STP-210 have three treads and a 9-inch rise, but fit different door openings. STP-211 and STP-214 have four treads and an 8-inch rise. Neither tread count nor the product photograph alone is enough to choose a replacement.

The manufacturer qualifier illustrates the threshold, doorframe flanges, skirt clearance, hinge mounting area and gas-strut clearance beside the entrance. It also explains how to measure the step height before selecting a model.

Check the doorway and wall before ordering

Threshold clearanceAllow the factory-specified threshold rise of ⅝–¾ inch and at least ⅜ inch below the entry and screen doors, as shown in MORryde's qualifier.

Hinge and strut spaceCheck both side-wall clearances and the depth behind the doorway flange. These steps require more side clearance than the standard folding StepAbove.

Interior wallThe assembly is intended for residential RV applications with approximately 2-inch wall thickness. MORryde provides shims for specified thinner-wall installations.

Existing door hardwareAn interior step well, a protruding interior wall or a door strut that stops the door from fully opening can prevent installation.

MORryde specifically identifies DRV and Riverstone units among its known Strut Assist exclusions. Check the complete qualification guide for additional details. The manufacturer's instructions call for two people during installation.

Before fitting: Verify the original doorframe width, ground-to-threshold height, threshold, inside wall and side clearances. Do not operate the step while the entry door is closed. Follow the manufacturer's full installation procedure.
