Trying to figure out how it will all fit. It took a few tries and couple sets of brackets... at first we were going to put the hydro on the bottom... it worked out better up high in the end because the curve at the front of the trailer... the runabout hit that.

 
 
 
 
 
boat carts are on the door and under the runabout.
fuel can, club papers, and sponsor flyers, paper towels, sponger, wheel block and funnel storage
these net storage things work awesome for holding everything... the one beside the motor, at the bottom, you just just see it, a small too bag that hangs on the wall and removes. ez-up along the wall, fold down shelf
white board, clip board, phone/race radio pocket, solar pannel for roof when parked

you can sort of see the small ropes that go down the side near the top of the wood that release the gate latches on the runabout handles. The hydro was installed the same way but too hard for people to help me get it out coming sponsons first. so now it has carpet covered wood (2x4) at the front that contours to the deck and hold the fron tin place. I just put that blue bungie on the back handle.

You can see the hitch pins for the rails... pull those, slide off the rails, rotate the mounts to the wall and the runabout rails slide into a pocket at the front and the back just pins into the floor. This way I can the trailer for my motorcycle or moving stuff too, and for sleeping at some races. Fits a double bed blow up mattress.

 
you can see you could fit more motors if wante, along the side. Even with the ez up there i could fit another easily, but I need a longer motor rack and one that would swing out is what I wanted. I have it drawn up but never got anyone to weld it up yet. I don't trust my welding for the motors... haha. As you can see from the pics of steel parts I can't weld very well... never had one lesson!! haha.
here it is hooked up...
sitting in the drive way. light enough to push around by myself most times... wife helps sometimes.
