Not sure if round is as good as rectangular. If you've done some research, which it appears you have, you will note there aren't any round hauling tanks for commerical hauling on the market. It may just be there there is less space wasted with a rectangular tank. A couple of compartments may be a plus on the large tank too (if it was rectangular).

Here's a rectangular plastic insulated tank I own from Rotomold in Minnesota.




I'm not a big fan of the bulkhead where a large PVC pipe is connected for quick release of fish. The fish don't always cooperate. I've had yellow perch that just flounder in the bottom of the tank once the water is released.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
