Anyone know if GM produced a dual battery setup for these trucks? If so, might you have PN#'s?

TIA,
Scott

They did but I don't know any part numbers. The 6.2 and 6.5 diesel trucks had dual batteries. All you would need would be the battery tray. You can make good top post cables cheaper than you can buy the factory ones. I really don't like side posts.

Other battery goes on the other side.
Same position, just different side of the truck.
You may have something in the way of installing the other tray but IIRC it is minor

^^^ on my 94 I think the only thing that gets relocated slightly would be the fuel vapor canister (charcoal can). Otherwise yes, a new tray (side specific) and cables.

I think I would wire in some kind of dual battery management system though to give more flexibility.

Both of my 99 Tahoes and my brothers 99 Suburban all had dual battery trays from the factory. They usually have an underhood storage box clipped into the driverside tray.

It varies.
I had a 97 that the storage box was bolted in the place of a battery tray.
I wanted to install it in my 90 but I had issues. I cannot remember what it was, but I believe the canister was one of the issues, and possibly my washer jug
