Double Alternators
Would most agree that on a Diesel, the option to have double alternators is a good idea if the option is available? Your thoughts please.

Hello,
New to the forum as I was looking for adivce for my next camper mod. I was going to add an inverter to run my 120vac fridge while towing and to have some(just a bit) AC power while dry camping.
Along with that I was wanting more battery so a couple of 6v 225ah batteries in series was in order. I was wanting to totally separate the truck battery and alternator from the RV side by adding a second alternator and a 2 pin Pollak connctor just for the RV batteries and inverter.
I really dont what to run anything else or have the whole camper on a massive inverter with a cross over. Just enought to give me the fridge or a few minutes of microwave use when stopped. My primary concern is separating the vehicle from the RV and enough power while idiling to run the inverter without getting into the batteries.
Yes I know the cost is excessive, but that aside, It seems pretty straight forward. What I am not sure of is should I externally regulate the power so I dont toast my batteries? we all know the alternator isnt the most efficient charger.
Also, will the alternator be able to power a 1000w inverter. I have looked and saw a few that were rated at 100+ amps at idle.
with that kind of idle amperage, I should be able to guarantee enough wattage to run a 5cuft fridge without getting into the batteries and have enough reserve to shut the truck off when I stop for an hour or so.
So it would seem that if I just took the alternator (with the proper ga wire) directly to the RV batteries via the 2 pin Pollack, common my grounds, and then tied the inverter directly to the batteries, it should be isolated from the vehicle batteries and electrical and provide enough power to charge and run the inverter. Should I get an external Regulator/charger?
