The arkpak sounds like what I'm looking for. Spendy, but gives me what I need as a house battery. I need to read up on this more and find some you tube videos as I'm confused by where and how you mount it and connect to the alternator for charging, but I'll figure it out.
But back to my dual purpose battery question. The EdgeStar has no options to chose different voltages so once the battery drops to a certain voltage the fridge shuts off and the jeep will still start. That scenario I've been through many times with no issues. My question is with the dual purpose that have the deep cycle option does the voltage remain high enough throughout the draining process to see the benefit of the additional reserve power? Does the voltage on the battery stay above 11 volts for example throughout use thus ensuring the full benefit of the additional amp hours. The specs say the EdgeStar will run when the voltage gets as low as 10.5, but from testing voltages my fridge seems to cut off in the high 11's like around 11.8. This may be an issue with the cooler itself not working correctly. I'm trying to figure out how much time I will get before the deep cycle voltage drops into the 11's.
Thanks!

While it could be hooked up to the alternator via a solenoid that is really defeating the purpose of the Arkpak being portable.
I think I already posted this but here are some comparisons. Your EdgeStar may not run as efficiently as the ARB. http://www.arkportablepower.com/blo...reezer-and-battery-life-what-you-need-to-know
The table in the article shows the information you need to know. All of it is not an exact science because your fridge does not normally attempt to cool 24/7.
From the article, "NOTE: These times assume you discharge the deep-cycle battery 70% (30% of total charge remaining), and they assume that your battery has 100% of its' listed capacity. Therefore, you should view these times as theoretical maximums and discount them a few hours to make sure you don't ruin your battery by over-discharging it."
This is also a good article to read, http://www.solar-electric.com/deep-cycle-battery-faq.html A battery is at 30% when it is around 11.75 volts. You can do a search for State of Charge to see various tables describing this.
