Iceless Coolers And 12V Coffee Makers

I personally went through 2 colemans in three months..went with Koolatron..no issues. As far as coffee, if you buy fuel regularly from same chain you get free coffee, buy enough fuel every month you get coffee and showers free, I haven't paid for coffee yet. I have a thermos and fill when its empty.

As long as you keep the fans and the air circulation areas clean, the cooler should last quite a long time. The "Heat Pump" part is solid state and should last pretty much indefinitely. The better quality coolers, I remember being able to buy fan motors and blades to get back up and running if a part wore out. I've had the same cooler for over 20 years and still haven't had to replace any parts yet either, I guess I'm just lucky and got a good one?

I do have an APU and an inverter. But it really doesn't take too much energy. It turns on about once or twice per day. It stays off until the internal temperature drops too much. So if I set it at 36 it'll turn on at 38 to recool itself. It takes about 10 seconds for it to get back to set temperature. I've never had my APU kick on because the frig sucked the batteries, well, not that I've noticed anyways.

Thanks, I was wondering how well that would work. I was always under the impression that any heat pump that uses a compressor also uses a LOT of power, hence why it costs a small fortune to air condition the house all summer long. I'd guess as long as the frig is insulated well enough and you don't open it all the time, then it only has to maintain the temp at whatever you set it at.

TWIC:

Transportation Worker Identification Credential

Truck drivers who regularly pick up from or deliver to the shipping ports will often be required to carry a TWIC card.

Your TWIC is a tamper-resistant biometric card which acts as both your identification in secure areas, as well as an indicator of you having passed the necessary security clearance. TWIC cards are valid for five years. The issuance of TWIC cards is overseen by the Transportation Security Administration and the Department of Homeland Security.

APU:

Auxiliary Power Unit

On tractor trailers, and APU is a small diesel engine that powers a heat and air conditioning unit while charging the truck's main batteries at the same time. This allows the driver to remain comfortable in the cab and have access to electric power without running the main truck engine.

Having an APU helps save money in fuel costs and saves wear and tear on the main engine, though they tend to be expensive to install and maintain. Therefore only a very small percentage of the trucks on the road today come equipped with an APU.
