That's an awesome van!
I can report back that I had a few fights with filler. I won some fights and filler won some.
Wild goose person is coming first Monday of next month.
I got new batch in the bright tank and I carbonated it to 2.7 volumes (10 psi @ 32F).
I am filling in the walking cooler on one filler only. With 2.7 volumes carbonation it appears to run better.
So far it had been prety frustrating experience.
People like the cans thou so this is a positive side.
