The Dometic DM2882RB1 is an 8 cubic foot double door like the RM3862, but the RM3862 is a 3-way unit and the cutout and venting can differ between the two. Before you buy, compare the DM2882's cutout dimensions to your opening, and send us your RM3862 product number so we can confirm. You can also see all our new Dometic refrigerators. 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.
