I watched several videos from the Liz Amazing YT-link you provided — very thoughtful content from two obviously-compatible sunbirders.

Her overall recommendations tend to recommend older, well-taken-care-of models over the newer less-expensive trash being mass-produced. Get a PROFESSIONAL INSPECTION before purchasing any RV particularly if your first purchase, and buy from a local person (instead of a dealership).

Really loved that some of Liz's most-popular videos weren't about RVs, particularly her Introduction to Electric Bicycles (helpful as we've gotten older).

By least-favorite brother (maker of terrible decisions™) lived in an RV for about two years, and it was absolutely embarassing to the neighborhood... just a squalor'd pig-stye.

If anybody near Chattanooga wants to restore an old Airstream, I know a guy... [that owns a dozen, variously delapidated]

Tangent... I've always thought a custom resto-mod Airstream Bambi would make for a rad little travel trailer. Scrap the wet bath, ditch the propane, add a pile of LiFePo4 batteries and flexible solar, run it all off 12V. Probably end up costing $60k or more, so probably never happen. Oh well.
