Sean, you might take a look at Magnum's auto generator start. They have two models - one that interfaces with their inverters and another that is standalone (http://magnumenergy.com/auto-generator-start-stand-alone-me-ags-s/).
I would be very nervous about the reliability of auto start when I was away for more than a few hours. Whether I used auto start or not, I would opt for an alarm system that could call my phone in the event of a malfunction.
Would search for the DynaGen ES52 manual or I can Email it with an address.

The web page specifically says this requires a land line. I assume only the sensors themselves are wireless.There are a number of power outage alarms that send alerts via cellular, but they seem to cost $200 and up.

If I read the price list right, that one is about $90, this one (simpler but looks good) is $70.
I am installing a 12kw Wrico Genset into my truck. It is only 36" long and uses a 3cylinder Kubota. It uses a 13kw head, but Dick Wright derated it to 12kw because of the engine.With Diesel engines, there is very little difference in running a small engine or a large engine fuel wise (for instance, you can get just about the same fuel mileage in a truck with a 350hp as with a 600hp-if driven the same). I would NOT use another APU in addition to the Diesel genset-just a waste of space and weight. Good Luck, TomC
