Don't talk yourself out of it - embrace the inevitable - if they are priced right that isThe package the stands like that to cut cost. Its easier to include the duplicate white/black section and then send you the correct side panel & doors, rather than keeping two seperate main stand components in the warehouse. Its irritating, because they dont tell you that anywhere. I made a call to RedSea to figure out what the heck was going on when I first set up mine, and thats what I was told.
I envy you for having two reefers and looking to add a third. Those xxLs are looking nice, but Im having to constantly talk myself out of it.
