For those who would rather order the exact same glycol that nüCamp uses in the factory, you can now order it through Amazon (but it is still available through Awesome Elsie in Parts at nüCamp!). Be sure to order this exact name on Amazon, per Marvin in Warranty:

As for whether the glycol shipped/recommended by nucamp is concentrated or not, I will defer to somebody who has recently ordered it. It is in my to-do list right now. I am guessing it says on the bottle though.
