Most of the info I can find on them says 2 1/2 feet deep, but has dimensions of 6x4x2.5, so even if I were to buy the 6x6x2 to give more space lengthwise, it still wouldn't be enough?
I understand what you're saying, I'm just trying to figure it all out. 6x6x2 seems like much more room than 6x4x2.5 that I usually see listed in care sheets. Not trying to be argumentive at all!
