“Advice on towing a car” is a very broad topic, because you have flat (four-down) towing, dolly towing, flat bed trailer towing, automatic or manual transmission preference, etc. I suggest you first check out this annual guide to dinghy towing: https://www.motorhome.com/download-dinghy-guides/
Then come back with specific questions. It first looks overwhelming, because it is overwhelming. Towing a car is not as simple as towing a trailer.
You mentioned “towing a CRV” in your title. Check the above guides for what model years with automatic transmissions are compatible with flat towing. Late model CRVs cannot be flat towed with their CVT transmission.
