Stairs, grab-rails, etc. can prove to be significant safety hazards as evidenced by many of the comments on this thread. Our Raptor 3712 is among larger units which seem to be getting a little higher off the ground with each new design. The total drop from entry floor to the ground as well as the angle of the stairs and the "abnormal rise" between stairs can be problematic. After the DW fractured an ankle coming down the front entry stairs, I started looking for a solution. A rubber-suit similar to the one worn by the the Michelein Tire guy did not meet the fashion requirments of the DW.
Elkhart Tool & Die in Elkart, Indiana makes replacement stairs to fit most RV units. We purchased their Quadra-Step (a four step unit vs. the factory 3 steps) With a rise of approximately 7-inches between stairs, the stair assembly is much closer to a normal residential step and easier to ascend and descend. The unit is 27" x 12-3/16" x 15-3/4" and bolted right into the camper stairwell box. The company pre-drilled all mounting holes on either side of the mounting bracket with extra holes drilled to facilitate height and depth adjustement. This allows the stair unit to fit many campers. Two hour installation doing it myself. A second person to assist in steadying stairs while bolts were put in place would have made the process a little quicker. Hardest part is getting wrenches in place to loosen the old mounting bolts and tightenup the new ones.The Quadra-step is heavy-duty and well constructed. The company website shows a photo and a detailed diagram of the stair unit with dimensions so you can pretty much ensure it will fit your unit before purchase. A web search for Elkhart Tool & Die Co. will locate their website.
Last time I checked (April 2011) the Quadra-Step could be purchased directlyfrom the manufacturer for $224.84 plus shipping. Thinking about adding a second Quadra-Step to the rear entry door this year.
