The flat Plano boxes are great. Carry the reels in padding like socks with you spare jacket or vest wrapped around them.
Rods are a problem. You really need tubes for them or you will be smashing the guides and rod tips off of them all the time.

You might be better making a case to hold the rods on the ATV rack and getting another small trunk for the tackle.
