The Stromberg Carlson PA-150 and PA-275 are freestanding, die-cast aluminum RV steps with the same 19 × 14-inch platform and a manufacturer-rated 1,000 lb capacity. They differ at their legs: PA-150 has a folding fixed-height design, while PA-275 provides three independently adjustable leg-height settings.

How to choose between them
PA-150 — folding fixed-height legs
With the legs extended, the platform stands 8⅛ inches tall. The manufacturer also permits low use at 3⅛ inches with the legs folded.
PA-275 — three adjustable heights
Each leg has its own height adjustment so the platform can be set between 7³⁄₁₆ and 8⁹⁄₁₆ inches on suitable ground.
Both — die-cast platform
The same grooved 19 × 14-inch surface and solid-bottom feet help provide secure contact when correctly positioned.
Original identification reference; figures describe step heights rather than a scaled drawing or installation template.
Choose PA-150 when a consistent 8⅛-inch platform height, or the manufacturer's permitted 3⅛-inch folded use, suits the entryway. Choose PA-275 when independent leg adjustment is useful for achieving a stable tread height. Neither unit is meant to be permanently attached to the trailer as a replacement for its built-in folding step assembly.

Stromberg identifies PA-675 as the replacement adjustable leg for the PA-275. That number refers to a leg service component, not a complete platform step. Older welded platform steps—such as PA-100 and PA-250—have different replacement-part families and should not be treated as compatible merely because they are similar in size.
Before using a portable step
- Measure the vertical distance from the ground to the trailer's lowest permanent entry tread, then choose a suitable platform height.
- Place the step on a firm, level surface and ensure all four feet are supported without rocking or sliding.
- On PA-275, verify each adjustable leg is properly locked at its selected height before stepping onto the platform.
- Check entry-door swing, handrail reach and clearance around the existing steps. Remove and stow the portable step before travel.
