I recently had to remove the main floor hatch to install a new fuel gauge sender with associated wiring and noticed the large area where a 2nd fuel tank would be located. Has anyone thought about putting in a hinged floor hatch and using this space? I am thinking that I could use this as a large fish box if I build a fiberglass liner and install a pump to drain it out. Just tossing out the idea to see if anyone has done something similar to this while I wait for the lakes to freeze over so I can do some ice fishing.
