This may blow your mind away. :yes:
When I was still doing the FW thing, (selling to LFS) I had alittle oner 1,300 gal in a 14x70 trailer house. At 8 lbs per gal, thats 10,400 lbs. Add to that the weight of the tanks, gravel.
I would estimate 6-7 tons. :thinking:
I wouldn't recomend doing this.
Everything held, but I think that was the limit.
