A:AnswerThe shipping box is rather large. I had a hard time sitting it in my jeep commander. There's no way it will fit in a car. You can rent a u-haul van for 20 buck. No worries. But it, drink, and be happy!
A:Answertoo much head can result from the tower being hotter than the beer that is going through it. That can be solved by getting a tower cooler from an online vendor like Amazon. The other cause can be too much CO2 as you suggest. turning it down will show if this is the cause.
A:AnswerIf both the kegs you have in mind come in the tall slim kegs - them yes it is possible to have both the coors and Miller in the kegerator with this set up - if they are the short kegs I don't see how it would work - not enough to room for the lines to be without getting pinched
A:AnswerKegs come preasurized but as you pour beer the preasure would slowly be less and less. CO2 into the tank maintains carbonation so you don't have flat beer. You will have to buy different keg connectors for cornelius kegs that many home brewers use.
A:AnswerTricky question as the inside area is irregular. 18 1/2" for the majority of it. Some small parts about 1" deeper. There is also a shelf moulded in the left rear lower corner area for a co2 bottle that measures 4 1/2" deep by 3 1/2" wide by 8 1/8" tall. Then it tapers down to 1" at the halfway point across the back and stays that way to the right rear corner. There is also a provision to install the co2 bottle on the rear outside on a mount that comes with it. That will allow more space inside. Good luck.
A:AnswerI was able to get multiple 1/4 and 1/6 kegs in my kegerator. Its not really a brand thing.
