I think the Kick panels on the RL cases are the easiest of all frozen cases to get off/on...(call me crazy)
The only real bad Hussmann cases I can think of and cuss out loud is the old RHFA cases. (Or maybe it's RFHA)
They have the drains on the far right side and it's only about the size of a nickel. I think a sunflower seed shell 1/2 can dam the thing up for a total ice up.
I have about 15 stores with these.
I'd really like to see that Superplus scroll rack
