i put my main battery, my secondary battery for my system and my battery isolator all in teh bed of my truck, i would not recomend putting them behind your seats in the cab just in case something were to happen, and if you put them in the bed be careful where you mount them, if you mount them on the frame keep in mind batteries can get heavy, my friend bought a truck off a guy on this site that had dro's with all the batterys in the back of the bed right against the tailgate basically and it cracked the frame, the asshole on here failed to mention that to my friend when he sold it to him
so just be careful where you put them
