I needing some ideas for the battery I tried to fit in the next to the engine and fab up a tray but not much room for spark plug removals no room under the cab
what about in the cab do you guys have any pic

 

I mounted Optima 6 Volts on each side of the vehicle outside the frame just behind the cab. I modified Optima 6V sized brackets from Speedway. They are connected in series with 1/0 cable with a master shut off in the cab and power terminals on the firewall.

Pricey, but the set-up works great and the batteries last years between replacement.

 

thanks Ernie

 

I used a frame mounted drop down battery box from CPP. Easy install and looks good. (polished stainless)
