I used 2" foam above the bottom plastic after I found most of the fiberglass insulation was wet and starting to mold. The lower skin was resting on the axel. I then used self tapping screws with fender washers to fasten the belly skin up. I also added screws in between all the screws on each side to try to keep the water out. I used foam spray and taped up all holes to finish off the sealing of the belly skin. 320RS has 1,000 miles and is just year old this Oct. 2015.
