How do you recommend building the floor on a Tiny House On Wheels (THOW)?

There are lots of ways to build the floor on a tiny house trailer, and lots of pros and cons to different combinations of flooring materials for a tiny house on wheels application. We have a Unit on building the floor and material choices in the Online Course, as well as a flooring topic within the advanced tiny house course Deep Dive Tiny House Workshops. For suggestions on the basic subfloor build up on a Fred’s Tiny House Trailer, see this demonstration video, time stamp 2:31.
