An FX5 will literally blow the top off of the cooler. I put one in a 35 gallon drum one time just to prove it worked, water went everywhere and the tub about flew off the car trailer I had it setting on. If anything get a battery air pack and a corner filter like they use for fry. If it were me I would sedate with bag buddies, restrict food 24 hrs prior to, and up to 5 days during transport. But that's just me.
