Dyna Span floors in Keystone travel trailers


New Member
I am looking at Keystone trailers, and have questions about their floor system, using Dura Span. As I understand it is a laminated 5/8" OSB based product. Looked at a Residence at a camping show and thought the floor felt a bit spongy, with noticeable sag in certain areas as an adult walked across. Anyone have any experience?

Pros? Cons?
