I love Fustis!
When I outfitted our Airstream last year I spent way too much time finding ways to use Stainless Steel, Glass or Silicone for everything that would touch anything we ate or drank. ...trying to limit the number of funky chemicals we take in for health reasons.
My original setup was a 5 liter Minox Fusti for the fridge and a 4 gallon-ish Minox Fusti for the counter (or in a cabinet). We abandoned the fridge option pretty quickly, though because the flow rate out of the little Fusti was really slow and it took forever to fill a glass - with the fridge door open the whole time.
The last few trips we've been keeping the 4 gallon Fusti in the truck and using it to refill the 5 liter one, which lives on the counter by the sink. I've been frustrated by the flow rate on the little one still (the big one has a faster flow rate) so I'll be looking into ways to fix that. Also, we're selling our house and moving in to the airstream fulltime soon, so it'll be interesting to see what setup we settle on after fulltiming for a while!
We got ours together from the Olive Oil Source Wholesale Store. The combined cost was just enough to meet their minimum order requirement so we saved some $$$ by getting their wholesale prices.
