Make sure the bags you get have extra ports on the top or you can install your own if doing a cross pump setup.. I spent a lot of wasted time trying to figure out the perfect setup, I only have goofies every once in a while so I use my 4th pump for under the seat, we still use a extra bag and tsunami pump to fill that, may plan was to have a line from the under seat bag to a hose to fill extra bags.. It's in the to do list.. you can't go wrong with any setup..
