Don't recommend the daystar spacer lift, much better to get coils, you don't have to change the shocks, but it is recommended for the rear as you can top out the original ones with a lift.
Duel batteries ,I put mine under my drivers seat ,most go in the rear storage compartments , a couple of guys fabbed up a shelf under the car behind the transfer case.
The V6 does have a thermo fan in the cowel behind the radiator, you should be able to hear it going, not sure if when the vehicle is hot, and you shut down the engine, then turn the ignition back on without starting if the fan comes on?
