Crucially, even with a manual transmission, you must consult your owner's manual or a Jeep CJ7 specific towing guide. There might be specific procedures, limitations, or recommendations for four-down towing with this particular model and engine. Simply assuming it's okay based on general guidelines is risky. Damage to the transmission is possible even with a manual transmission if not done correctly.
Therefore, while it *might* be possible to tow it four-down, you absolutely cannot definitively say so without checking the appropriate documentation for your specific vehicle. The safest bet is to assume it needs a trailer unless explicitly stated otherwise in a reliable source.
