One large inverter or 2-3 small ones?
So as I get closer to adding solar (or at least a larger battery bank) to my RV, I have more questions than I started with! Big thanks to the folks who have helped me along so far. I found a great...

Hi Jeff,
The catastrophic failure fuse should be as close to the battery bank as is humanly possible.
Flow chart:
Battery buss-->fuse-->switch-->inverter-->120 volt output-->30 amp female plug.
The best of the best inverters are about 88% efficient when running "flat out". So to get 1000 watts out 12% more watts must come from the battery bank. That is about 1136 watts. Amps are watts divided by voltage. That works out to 94.7 amps @ 12 volts.
Since surge values on inverters are typically double their wattage, it would make sense to fuse at 200 amps, SO LONG AS THE WIRE CAN SAFELY CARRY that many amps. Otherwise fuse to protect the wire.
DAMHIK to fuse at surge value, *blush* LOL.
I prefer 12 volt jars--but many disagree with that. As I mentioned earlier you might increase total capacity by 1/5 by doing so. The ultimate battery bank is six TWO volt cells. OUCH on pocket book to do so. However, the six volt units you have chosen are also in the "OUCH" region.
Since you are going AGM, the specific recommendations for charging from the battery maker need to be followed to the letter. I'd be very tempted for that reason to use an agm starter battery so the alternator charging circuit could be correctly adjusted. OR use the external module I mentioned earlier for the care and feeding of the house battery bank.
As to camping world doing this right and safely--I would be VERY specific about having them use the largest possible wire between the battery bank and the inverter. I'd also be very specific about them wiring the battery bank in a balanced manner.
