I would like to know if the Reprieve 15 x 30 x 54" can be used with an expandable liner. If so, I would also like to know how deep the liner can go. On your website the expandable liner you offer says that the liner is expandable up to 72" however on the wil-bar dig sheet it shows a maximum depth of 2-6 plus the wall height which is 84" all together.
Thanks
