PBinWA, since I about hijacked your thread, I should try to contribute.
Not sure if I answer you question, but I can offer some things to think about.
I agree with the previous posters on keeping the wires short and big. If you intend to occasionally tap your inverters capacity, your talking some serious current. Just looked, that inverter has a peak of 4000 watts. That may be 300+ amps. Anyway we are talking about wires that start your truck. Where you will see the value in the big wires, is in voltage drop. Because your inverter will have a drop out voltage, you will get a little more capacity if you don't have as much voltage drop.
The problem here is that this would lead you to think about putting the inverter under the hood. This is really a harsh environment. The inverter needs to dissipate a lot of heat at high loads. It is likely to be very hot under your hood and will put the inverter into thermal overload quicker. Ultimately I think you would sacrifice longevity of the inverter.
Also it could probably get pretty wet. I am not familiar with the inverter, but I bet it doesn't want to be wet.
I liked EastTexFank technique also. A refinement of this idea could be to mount very large wires to special battery connectors, and bring a high current receptacle to an available space and mount in the front grill. You could also leave it under the hood until it is ready to use. This would likely assure you have a very good connection (better than battery cables). I am familiar with some nice high current connector that are on aircraft for boosting them(aircraft usually means $$$). There may also be welding connectors that can be used. Lot of folks here on TBN seem to know a lot about connectors, they may have suggestions. If you like this route and want help finding a reasonable connector, Let me know, I will help you look.
Good luck, hope that helped.
