It isn’t unusual at all for us to end up in a camp site where an extra step would be nice. We looked at different products in RV supply stores and also searched on line to see what was available. Finally, we settled on this exercise “step deck” from Walmart. The cost was less than the RV specific ones we found and it is almost exactly the same size as the RV steps. It can also be adjusted to two heights, 4″ or 6″, and is light weight. If you would like to carry an extra step “just in case” you might want to check out one of these.
