DIY changing Alde glycol

I have a 2018 Outback T@B 320s. I am seeking assistance with 2 issues related to my 3010 Alde heat system.

I have read what I hope to be ALL the related postings here, but still have a couple of questions.

1) Where is the "brass drain plug" so that I can drain and add new glycol? Above floor near/adjacent to the Alde unit? or under floor accessed from the outside/ground?
2) Is there a current 'fix' from Alde for the Alde 3010 high elevation noise? Does the noise get exponentially worse as one gains elevation, and not so pronounced at lower elevations... like 5500 to 6000 ft??

Thanks for any assistance !!
Happy 'glamping' Y'ALL !!!

    The glycol drain tube with the brass plug is under the TaB rear driver side.

    We had the high altitude Alde 3010 fix installed by the nuCamp repair dept.  It is a regulator that reduces propane flow to prevent the Alde from running rich.  I can’t speak to the noise as we had it installed prior to high elevation camping.  Contact a dealer for the fix.  It is not a difficult modification.

    On my 2017, all the way up to 8000 ft, the Alde doesn't make any different noise than it does at sea level.  Not everyone had the "Alde Freight Train."

    I have a 2017 Tab 320S.  My drain tube for the Alde does not have a brass drain plug--it appears to be something plastic--it is under the tab rear drivers side and has a small hose clamp on it.  I do not experience any significant change in noise from the Alde when at high altitude.  I'm in Colorado and we often camp at 8,500 +.  It rumbles a bit when it's heating up but nothing significant.  I bought mine used so I don't know if any fix was done previously.

    The DIY document I posted here has photos of both styles of drain plug on page 4.
