Cooler Size for Transporting Crabs?

[djmase]

I'm looking to transport four bushels of No.1 crabs and wondering if anyone knows how big a cooler (or two) I need to fit all the crabs and gel packs in there?
Are two 150-quart coolers much more than necessary? Something like below:

Thanks for the help.

two 150's ought to be fine. I fit 1 bu.in a 72,and still have room for more.

Thanks, very much.

use frozen 2 liter bottles instead of gel packs.  They will hold up better and last longer
