Alde glycol container, new, need to buy

An expansion tank?

I just ordered some things from Missouri Teardrops.  Talk to Dana or Barb there.  They had my Alde circuit board in my hands in less than a week.  They want a photo of the item you want, and the VIN number of your trailer.  They just want to make sure of what you need and what they need to order for you.

Many owners here have used them for parts.
