Well... space issues or not I surely wouldn't spend $500+ on something that keeps 1 gallon of milk cold. A good insulated cooler/ice will do just as good of a job and is about 10x cheaper.
Some of you must not go through alot of milk. Alot of our recent events have us using 5-6 gallons of milk and this is in a 2-3 hr time frame. In our van we have a full size refrigerator, 22 cu ft, with the capacity of holding around 11 gallons of milk, along with bottled water, soda, half-n-half, etc. and we need all the room we can get for our dairy needs.
CCafe... define what you consider a ton of reasons... would that be 2,000 of them as in 2,000 lbs. in a ton? LATER!
