I walk on the roof of my 2013 Cougar 30fkv (Xlite) all the time, and it doesn't have a ladder. In fact, when I had it into the dealer last for inspection, the inspector climbed up and looked over the roof and pointed out to me a couple places where I needed to add a little sealant. Don't know if all Keystone trailers have a walkable roof, but that was one thing I specifically wanted to know when I bought it, and they showed me the brochure which depicted just how the roof is constructed and it's easy to see why one could walk on it.
