I am looking to do some type of recycled rubber over an aluminum floor in my trailer.  Thoughts, types, pros, cons?

Werm Flooring is the way to go! It is the only one that doesnt let usrine or fecies touch the floor. It completely seals it off and is super easy to clean, you just hose/power wash it out. Its also the only one you can use shavings on! We pulled a differnt one out of a trailer we bought, they drilled a billion holes in the floor that all ended up plugged and urine just sat on the floor. It was so gross and oxidized the floor 

Thank you.  I just got a quote on the werm flooring.
