We want to put a new fridge in our boat. The Norcold DE 828 that's in there now shows specs with a cut out of 51 7/8". Any of the replacement models we're looking at (Norcold DE 0061, Vitfrigo 2600, Nova Kool RFU 9000 or 8220) all show a cut out of 52 7/8". Does anyone know if there is an inch of wiggle room on the 3207? I pulled out the old one last summer to try and clean behind it and check things out and, if I remember correctly, there isn't much room. I can't get to the boat right now because it's under 3' of snow. If I am going to be able to replace it, I'm going to need to order something fairly soon to get it to Northern Ontario in time for spring break up. Thanks for the help.
