This is a 12V system and 6', not 6V or whatever chart you are using to come up with the wrong answer. 4 AWG (not 4/0) is good for 200 amps and 20'... more than enough for the OP's system in a small Class A with probably a 1000W inverter. Even if he has a 2000W (167 amps at 12V) inverter a 4 gauge wire is still large enough.
OP, the short jumpers between the two 6V batteries and the negative ones to the frame can be 4 AWG as there is no good reason to run two 6' wires. If you have a 2000W inverter then to make some on here happy... 2 AWG for the 6' run otherwise 4 AWG. If you were using four 12V batteries then two 6' wires so you could balance the system would be worth it.
So prove me wrong:
Voltage Drop CalcObviously its a 12V system built with 6V batteries, and the TOTAL RT length is 12', not 6'. If he wants to use the frame, great, but thats still not zero. If you want to run a 2K inverter on 4ga good for you. I can tell you for a fact that Magnum and Dimensions require at least 3/0 for a 12' RT run. Doesn't matter what the cable is rated for, and you are clearly on the edge with that. Its the drop that the appliances downstream can stand.
