Ideas for mounting fire extinguisher

[theseeker]

So I have to some how mount a 30lb fire extinguisher in my f150 Ive got the mounting bracket but it seems that bolting something that heavy to the box of the truck itself would eventually destroy the inside of the box from rattling around. Its got to go in one of the back corners so I was looking for ideas of how to secure this thing cause I am really dreading drilling holes in my truck.

I made a flat steel plate 6'' wide and 10'' tall then riveted it to the box with a bunch of rivets then mounted the braket to that been in there since 2000.

No issues yet plus I made the ext bracket quick detach from the plate so it can come off and go in the cab at nite or in the hotel so the darn retards can set it off all over my truck. AGAIN.
