@Harolo - Winterizing does not impact the glycol heating area of the Alde unit. Not sure you how you winterized, but if you used the Nautilus and you put antifreeze in your plumbing, just follow the instructions for dewinterizing and sanitizing with the Nautilus and no antifreeze should enter the Alde water tank. This will not involve the Alde glycol heating area of the unit.

The glycol used by nuCamp changed for all units manufactured after 1/4/21. Units prior to this time used Century Transfer fluid available on Amazon. Check the front A frame for a label that indicates manufacture date. What color is the fluid?

After the 1/4/21 change over, nüCamp used the new Rhomar fluid, which is available from nuCamp, via most of nüCamp dealers.

I have a 2020 T@b 400 with the older yellow glycol. So far i have only added about a cup to keep it between the min and max lines. Can I replace the yellow glycol with the new Rhomar fluid? Also how often should the yellow glycol be changed and why?

There are several discussions on this subject search for Alde glycol change.
The glycol should be changed once every two years.
You can replace the older Century TF with the new Rhomar fluid, but this is an involved process, as the old fluid needs to be completely flushed out of the Alade system, best done by a TaB or Airstream dealer.

@Jbreunig - here is the discussion and a copy of the PDF created by ScottG for a DIY Alde glycol drain, flush and refill.
