Highly paid and well funded engineers worked this out for you already, just use some recycled round fuel tank brackets and bolt 'em to the sides of the frame and you're good to go.
So I have some tank mounting brackets but they don't wrap completely around the tank so I wouldn't be able to bolt both ends to the same frame rail and I don't see anything other than the frame rail I can bolt to. It would be nice if I could put it between the frame rails but the under bus storage makes that impossible. So if I just had longer straps could I then secure the tank by wrapping the straps around the tank completely and having both ends of each strap attach to the same side or face of the frame rail?
