We tow a '05 Odyssey either on a dolly or four down. Yes, we do know Honda say's it's not towable four down. They even paid us about $2,200 not to tow it four down. However, over the years I've talked to a number of owners who were towing them four down so I've started doing it again. Did end up with a dead battery after towing to Phoenix last year so I added a charge line. Used 10 GA wire and 30 amp auto reset "fuses" at both ends. That protects the wiring since a short can occur at either end or the middle.
