Frequently asked
What is the HQ21-Balcony's balcony?
A folding deck that extends from the side of the trailer when parked, giving a private outdoor living platform. It folds back into the shell when towing. It's a flagship Black Series feature.
Why is the Bambi 20FB more expensive but smaller?
Airstream's aluminum monocoque construction costs more to build but resists rot, retains 70-85% of value over 10 years on resale, and weighs much less per square foot. The HQ21-Balcony uses conventional steel chassis construction.
Which is more capable off-grid?
The HQ21-Balcony - 600W solar plus 2,000W pure sine inverter standard. The Bambi 20FB has 100W solar with lithium battery; off-grid capable but for shorter durations or lower draw.
