Clev we must think a lot alike because right after we got our unit we did the same thing to the under side of ours. It is amazing how many holes and cracks you find in these things. We also took 1" 4X8 sheets of Owens Corning ridged insulation and put it between the floor joist in the pass thru storage area. Then covered that with Reflectix. I just feel like you can't have to much insulation in an RV. All this has made a big difference in our trailer and I feel like the added insulation in the front and rear caps tomorrow will just add to it.
