Gas Tank Hatch ?

[Islandtrader]

I am doing some pre-planning and would like a few comments.

I am replacing the entire cock pit sole.


When I put my new aluminum tank in I can lay the floor over the tank and have a large tank hatch(22*48) that would allow me to access and pull the tank any time (I would need to make the hatch). Or I can lay the panel down over the tank, with 2 access panels for the fittings,and sender. Just fasten (mechanical) and caulk the seams (easier). If I needed to pull tank I could, just need to pull up caulk.

There is not much space between floor and tank top, so storage is not an issue.

What does the real world think? Seal or Hatch.
