Electrical advice needed!

Will do!

 

Psshhh!!! 1st gen problems

But really, Monte is right. That would be a lot of drag man!

 

I haven't had a problem with my 2 700's and 2 500's

 

Horribly.

Take a 9" dinner plate and hold onto it out the window at 70mph.

Now take another one and hold it up front... even completely in front of the windshield.
There's very little airflow within the boundary layer. The boundary layer is very thin... outside of that, it doesn't matter what's behind it. The new item becomes the new windbreak and blows the aerodynamics (such as they are) of the entire cab.

 

2nd Gen should get plenty of flow from the lower valance.
Notice how much of the grille area is blocked?

 

Summers in the inland valleys where i live top 90-100+ in the summers, have not had and issue yet.

 

Correctamundo!

 

OP, why don't you start small, get a lightbar on the bumper and learn how to do lighting, one you get the hang of it it's pretty easy once you understand the theory and the numbers

 

I've got the lighting down. I've just never really taken time to learn the theory or numbers

 

Changing to a deep cycle battery for lighting shouldn't be required as long as the alternator can keep up with the load.
Here's a link to heavy duty alternators

Using the 270A alternator and allowing for only 80 % loading of the conductor, you will need to upgrade the alternator to battery wire, and ground wire to a 350 MCM conductor. That's effing huge.

Conductor sizing should be based on watts/volts= amps
Use a chart to determine wire gauge. However never load a conductor beyond 80%. You also need to up the gauge if its a longer run to compensate for the resistance of the conductor. If wiring two lights, eg with one conductor, you need to size it for the total load.

Fusing, relays, etc.

Gonna have to make a wiring diagram and plan it all in advance.
Be a fun project, but not cheap.

 

And it will take roughly 5 HP to drive the 270A alternator.

Maybe a CAI and Borla exhaust to compensate lol
