RV Repair: Repair a rubber roof, sportsmaster travel trailer, rubber roof

Question
We own a 1994 Sportsmaster Travel trailer.  When we bought the trailer it had had a previous leak in the rear passenger side and just a weekend ago we sprung a leak in the driver's front.  We know that the leak from before is fixed but the plywood is very soft and needs to be replaced.  The new leak, we have chaulked the hole shut but we also need to replace the plywood under there.  Do you have any suggestions for fixing this and also recovering the roof?

Answer
There really is not a good answer to this, since I can't see exactly what you are needing to replace. To put it simply, just start un-assembling things until you get to the part that needs to be replaced. At that point you will be able to see the extent of it, and know what kinds of materials you will need. Hope this helps at least a little.
Is it a metal roof or a rubber roof? Is the decking bad? I really need more information on the roof. What is the matter with it?
