What year is your truck, my roomates 89 had the battery on the passenger side and it didnt interfer with it laid out on 18s.
But on his 92 we moved it in the bed cause he wanted it back there. We used a typical plastic battery box from the part store it was about 20 bucks, and a few new battery terminals and went home depot and got some stranded 2/0 copper wire with a THHN Jacket, it has a good coating that resists alot of heat and sunlight and gas but yea the ground just goes to a clean spot on the frame with terminal that has a large hole on it.
Run the positive up front to where the old battery terminal was and cut that terminal off and put both of them in some sort of large wire coupling they got one called a polaris lug that has some No-Lox inside of it to prevent the wires from corrouding inside the lug.
Then just wrap it up with lots of electrical tape and go from there, I have know some people to use some of the streetwires battery termial boxes where you can branch off with several diffent wires, you might want to do something like that if your trying to show it off.
