My 2018 Keystone Carbon was built in late 2017. From the factory a serious hazard existed in these steps. I nearly fell to the floor below as did my granddaughter several times. You just don't expect 3 different step heights when going down stairs.
This videos details how I fixed this hazard. The end result looks and functions much better. I am very pleased with this outcome.
