JD - Don't know how much you are planing to load down the 2000W INVERTER but if you look at the specs on your two planned deep cycle batteries you may find they will only produce enough power to run your 2000WATT Inverter for just a few minutes if loaded down for the total 2000WATTS.
A standard 105AH deep cycle battery will only produce 12VDC@75AMPS for only 15 minutes or so before it gets down to its 50% charge state when you need to re-charge before doing damage to the battery.. Might get 30 minutes using two in parallel..
Large INVERTERS are very 12VDC power Hungry. You probably will have a 200AMP or more fuse between your battery system and the 2000WATT Inverter. That is alot of DC current... It may also require a heavy duty truck alternator setup to re-charge them like you indicated you wanted to do. A standard truck alternator may go up in blue smoke...
Just more things to think about...
