hey man it is a good drawing and good job you didn't get caught!
okay now on to your computer you want to add in... how mcuh power is this computer going to pack? like are you running a nvidia 790i mobo, with tri-sli (3 9800 video cards) with 8 gigs of ram? lmao man i am almost postive you don't need any more then 500watts to run this lmoa which = a 1900(that number could be off) power supply need for your whole truck, plus it is a truck so if i am not wrong stuff is already beffed up.
which is why i recommened a hc2000 extra battery, or if you wnt to overkill go with the 2400, rember shops, and company they wnat to sell you stuff, the more stuff the more profit! b/c money makes the world go around!
put it this way they make 740 PLUS shipping and handling for 2 1400 if you buy them retial, and for one hc2400 it is 500 plus shipping and handling saving of 240ish lol.

i purchased my kinetic hc2400 off of an forum and i got it for 290 shipped to my door! so just look around and you will be good to go man! other then that i think 2 1400 willl be massive overkill depending on what kind a compute ryou will be running! and since it is a truck pc i don't thin it should be anythign to fanzy, like it isn't a high end gaming machine i mean!
hit me back on this though man
and how much power did you tell them you need btw, like what did you tell them to make them say 2 1400hc? b/c for 2 mags you will need at least 2000 amps right?
