My old setup was a steel tub like Dragula's last pic and it had a plastic tank in it like Chris2412's and straps I made. The new setup, I bought an RCI 10 gal aluminum tank like Dragula's upper pic and I was going to sink it into the floor the same as in his pic. There are tabs on the side and they have to go to a tube frame. Does there have to be a bottom on it to be legal? (being an aluminum tank)

I dont have my book in front of me but if I recall
correctly you need a skid plate IF the bottom hangs
below the frame rail
EDIT
if the floor has been re worked.... check the book
