That's an odd thing to want to do. The battery characteristics are different for starting and long slow draining. Plus you would need some serious fat wire running to your truck starter. What is the reason for your idea?
Simplicity and weight savings. Being able to use the alternator for house battery charging without isolation, and getting rid of a starting battery that I don't really need.
AGM or FLA deep cycle batteries will easily start a vehicle if they are big enough, and they only need to be a little larger than the starting battery to account for slightly higher internal resistance. I was planning on ~3x the size so plenty of CCA.
I'd need big wires, but typical starter wires will work. I was planning to put the batteries behind the front seat of the cab.
But... that was AGMs. Thinking about it more, if I use LiFePO4 for the house I can probably forget about alternator charging, because they are not finicky about needing to be topped off the way AGMs are. Just need to make sure my panels and batteries are sized in excess of what I'll use.
