You did not mention the grounds. DID you check the grounds at both ends at the battery and the block!! The grounds will get you every time. Ya the stacked battery cable ends can be a pain. But I learned every time you service the truck put a wrench on them. Eventually they will stay tight. Get a digital volt ohm meter( DVOM) They have them for short money at Wal-Mart, Sears, Home Depot, Etc. Start at the battery and work to wards the engine look for a voltage drop and don't forget the GROUNDS. The 2/0 cable is a great idea but tough to work with down at the starter. Make sure the truck will not roll have some one hold the key in the crank position wiggle all the cables. Rap the starter with a hammer in the crank position. If it comes to life look for sparks at the connections That's where the problem is. Something to think about hope this helps.

thanks for the suggestions when it warms up on the weekend i'll check the grounds, get my better half out there to hold the key on and get my hammer kicking, and start looking for volt drops down the line.
