<div><font style="background-color: transparent;">Don't be torn. I'm doing all three of those things on mine. And don't forget the real reason for putting the bottles outside. Payload!!! Two HP air tanks and the brackets George specifies in the plans, I think it's nearly 150#. Call it 70 kilos. That's a whole 'nother person you could haul around. Or lots of gear (manips, sonar, comms, etc.).</font></div>

<div>Hatch closure from both sides deffenetly a good one. I would say adjustable exterior weights. I hate the idea on chucking weights on the floor and then sitting on them. I am torn between that and moving the hp air tanks to the exterior to allow alot more room on the inside.</div>
