The Stromberg Carlson PA-150 and PA-275 are portable, die-cast aluminum RV platform steps with the same 19 × 14-inch tread area and 1,000 lb capacity. Their legs work differently: the PA-150 folds to a low storage height, while the PA-275 has three adjustable leg positions. Compare the models and factory replacement-leg numbers below.

Replacement legs and step hardware
Stromberg Carlson identifies PA-0150 as the replacement leg for the PA-150, and PA-675 as the replacement leg for the PA-275. Because the adjustable mechanism is different, do not substitute one leg for the other. Each model uses rubber feet to help prevent sliding during use.
Choosing the right step for your RV
Use the PA-150 when a fixed 8⅛-inch step height and compact folded storage are suitable. The PA-275 provides height adjustment for varying surfaces. Place the step on stable ground and ensure all legs are firmly supported before using it.
