sorry for the wait, I never got an email saying there were posts in this thread.
The first time you remove the trim, it takes a while, as you are unsure of how things work exactly. The how-tos on this site help quite a bit. To pull up all the flooring, remove all the padding, clean everything, lay the eDead/DynaMat, cut and lay new matting, and replace the flooring will take you a full weekend's worth of work. The time really gets consumed in the details. I really focused on doing a really good job, so I took my time. Not like it's easy to re-do the eDead. That stuff gets real sticky fast. The Tsunami was much easier to re-do (the stuff two years ago was, anyways). Just the doors can be done in one day, easy. A lot of the time is spent learning what tools to use and how to get the results you want, also.
Hope this helps, if any more questions, let me know.
