The Polar N10 was designed to fit into the same size cutout as Norcold's 8 cubic foot models, so an N10DC is often a good replacement for an N811. You'll still want to compare the N10DC's cutout dimensions to your opening, and keep in mind that a 12V compressor fridge draws more 12V current than your N811, so your wiring and fuse may need to be upgraded. Our post on replacement refrigerators for the N811/ N821/ N841 covers this in more detail, and here's the N10DCBK. Since I can't confirm this 100% from here, please email us at info@rvfridgeguys.com or call 800-712-8822 with your model and serial number and we'll double-check it for you.
