UPDATE TO OP;
Realized I never came back and made a final note of appreciation to all those that responded to this post. Taking in a number of factors, we moved on and ended up purchasing a one owner, 2018 Classic M30 RQB still under factory warranty out in Las Vegas in Feb. of this year. Made a really great deal and actually purchased it for less than its NADA Commercial (Dealer's version) book trade-in value and which excluded a $23k full AM Solar Victron/LifePro Lithium set-up, ProPride 3P AS/WD Hitch, WeBoost, Apple TV, etc. etc. Our purchase included our having an NRVIA Certified Pre-Purchase Inspection which found nothing wrong or at issue other than an recently outstanding Factory TSB/Recall for the Alde Hydronic Heating system which was covered and performed by our closest Airstream Dealer once we returned home (1,700 miles) with it.
Again, Thanks to all whom responded.
