if you are going to idle alot then maybe an 8D battery? install a battery isolater so that your main batteries wont discharge if you are running your A/C with the engine off..

Thanks CK. I think I will do that with the alternator, my battery bank changed, I have 6-6v 305 Ah crown batteries on order. I do have a little hyundai inverter/generator however, think that would power it ok while I drove? I could always get an external tank for it.

I have an 250 amp alt I am installing, with a yet to be determined inverter and three 150 AH batteries. I still need to do a load analysis before I commit to the inverter but whatever the combo, it should be enough for my 12 volt fridge/freezer and 8000 BTU A/C......I hope.

If you get a chance, could you provide some details about the size and setup of your batteries, and the amp draw/duty cycle of the air conditioner? What kind of run times are you expecting maybe?

Our setup will be very simple:
underbelly inverter generator while driving to run A/C, fridge, and a couple of outlets for tablet/phone charging. Then, once we reach our destination, plugin to park power. We're only planning to travel to parks that have RV outlets, and shower facilities, anyway ;)

Ha, everybody knows teleporting takes two cords.

You're talking about a special duty cord when you're using the time machine.

Pfft!
My frequency fluid activated warp-driven space-time machine (copyright/patent pending) is DA BOMB!
Also, no cables required...

You're no fun! Right, but no fun.
So we mentioned generators, alternators and battery banks. Question: would you upgrade the alt., or custom mount a second one?
