Transporting tanks

[Dano]

There's probably many options here. I took a couple of 2 x 6's and cut 90 degree V-notches about 2/3 the depth of the board and spaced 9"-10" apart along the length. With notches facing upward and aligned, I spaced the 2 x's parallel and 19" apart with other 2 x's at the ends and all screwed together at the corners creating a rectangular frame.
I found laying tanks with the valve neck in the V-notch kept the tank from sliding length wise of the tank. Mine holds two tanks. I've added a third tank by just laying on the other two.
