If you REALLY want to tailgate.....you need one of these:
What is inside of it? This (plus ice):
What is that? 3 gallon version (instead of 5 gallon), and 16 gram version (instead of 15 pounds) of this:
The dual tap kegerator is the best...especially when you have both CO2 and Nitrogen tanks. And the best part is that you can direct transfer beer from the larger kegs into the smaller keg. As long as you keep it cold (max chill cooler does that) and keep it on CO2 (16 gram CO2 cartridge...similar to those in b.b.guns and for bicycles)...you can drink as much or as little as you want...and whatever you don't drink, you can direct transfer back into your main keg (or just throw the entire small keg in the fridge) because oxegen never came in contact with the beer. It will last for months.
Also, you can open up the corny kegs, fill them with rum and soda (or juice....or whatever)...close it up, purge the oxygen with CO2, and keep rum and cokes on tap....COLD. Nothing beats an icecold rum and coke...without ice!. The CO2 keeps it carbonated, so it does not go flat.
So...that Sahara that I'm looking at may never go rock-crawling...and may spend some time in a mall parking lot. But you can bet your ass that on a nice day...when I'm not on my motorcycle...the top will be off...and the mobile keg will be flowing!
