The RV step is a deceptively complicated object. Besides tread style, and width, depth and drop dimensions, steps vary based on the way they latch closed and the way they mount. For instance, vintage Airstream steps use cut outs in the outriggers as tracks. Newer versions come with their own tracks on the sides.
#1 didn't come with an original step. It was an older replacement model. Colin and I have been arguing about that damn step since I bought #1. He pushed me to look for an original. I said I didn't care how it looked and a new one is cheap...a lot cheaper than having him fabricate something. I have to be cost-conscious someplace and a non-original step seems like a good place.
But Colin is a perfectionist and he had installed enough old and new steps to argue that a properly restored vintage Airstream step not only looks unique but also works better than a new replacement.
Ultimately, the argument ended when my #2 Caravanner showed up with a good original step. It has been cut out of #2 and made to fit just like it should on the #1 chassis. Colin wins.
