I want to add a dual battery to my truck I have alot of electronics ill be adding
snow plow, safety light dual compressors for an on board air system dual amps . you get the picture.
My old chevy had a place for the second battery in the engine bay. I cant seem to find any location where to add in my new truck.
Worse comes to worse ill have to add it to the bed or maybe somewhere underneath ?

Thought, pictures if anyone has done this

Thanks

i know Dave aka Ramhunter9 did it on his old rig a while ago. think he had an after market air intake and put the battery where the air filter box was. just need to mount the battery holder. not sure how hard it was, i know you have to hook it upt to the alternator though

If you run a Vararam intake (works with the 2500 hemi), then that would open up the entire passenger side of the engine bay. Would be perfect for a second battery setup under the hood.
