If I were to put an 8000 lb. winch on my tj would i have enough power to run this off of one optima red top? Would i need an additional battery? What should i expect? Last, has anyone heard anything or have any experience with the black mountain winch? I saw one on Ebay with plate, snatch, roller, and winch for 450.00. Would it be wise to go with an off-name winch?
