I also have a 16' NRS. I saw Kazak's set up and wondered how his cans fit below the tubes. His floor must be lower, I sometimes run 5 cans in the first or second bay and they stick up about 2" to 3" above the frame. I am going to lower my drop bag and see if I can get the cans any lower.
I have been rigging a homemade deck/ table over the cans and that raises them up to the same height as my cooler which is about 18" tall. This makes a huge 4'x7' lounge area covered with two pacos.
