The Furrion Arctic 8 cu. ft. matte black door panels (P/N C-FCR08DCGTA-A02) are currently out of stock but are expected to be available within approximately 4-5 weeks. The alternative 10 cu. ft. panels (P/N C-FCR10DCGTA-A02) you mentioned are made of stainless steel and are available in matte black. While the freezer panels are identical, the refrigerator panel for the 10 cu. ft. model is about 7 inches longer than the 8 cu. ft. version. It is possible to modify the larger panel by cutting it down to size; however, care must be taken to ensure that the panel’s structural integrity and functionality are not compromised. If modifications are not preferable, you may wait for the correct panels to restock or cancel the current order to place a new one when needed. For any additional assistance or questions on compatibility and ordering, Elkhart RV Parts is available to help.
