Here is the deal.
I have a 3 tap keg fridge in the basement that I love, hooked up to a 20lb CO2 tank.
On July 5th, we are having a large bbq, and I will have 5 beers ready to serve (it's been hard not to touch them...patience is definately a virtue). I thought I would allow access to the basement for the 3 taps, and have a serving box outside with 2 more selections on tap.
On the following weekend, I will be renting a cottage for a week with family, and would like to take brew there as well. Perhaps a way to make two kegs portable?
So, I need to find the most economical way to serve from 2 kegs, have it be portable, and able to withstand being outdoors in summer temperatures. I would like to avoid purchasing an extra CO2 tank and regulator, if possible.
I have a surplus of foam board insulation, so I was thinking of a 2 chamber insulated box that fills with ice, but I have no experience in serving kegs away from the keggerator, as well as cooling 10g with ice only. Can I get by with ice for cooling, and those little CO2 handheld injectors for serving, or would the cost of ice and CO2 cartriges equal the cost of a 5lb tank + regulator?
I'm a pretty good DIY guy(although I wish I was Yuri!) , but I need some advise on which direction to go.
