Pete - Yep, inside the truck lol... but no, that's not the final form... I needed to get them into play and that was the best way I could immediately "charge" them. This is closer to what the end product will look like...
Looks like it's gonna hold just shy of twice what I have currently... 48ea 500mL, or just over 6 gallons, so about 12. Need is somewhere around 20... at some point the weight and space starts to count against me... the jugs up in the attic in the "spread out" pic are a gallon a pop, 10 in play.
Still working out details but air flow end to end, eventually bidirectional if I can make it practical.
Exact soda was chosen solely for bottle attributes, but yes, haha caffeine was a deal breaker. These were the only ones that fit the bill, were available in numbers at the moment, and caffeine free. I'm slowly replacing it with collected condensate from the aircon as I drink it.
Wolv - In a nutshell... lol "right where the lid is" haha
I'm looking at ways to support the equivalent of the curtain that I trap heat with in the winter for this... it's gonna be interesting if I can work it out, to say the least haha
