Interesting that you're seeing under 500 Wh/mi with the Alto - Ohmman's chart showed the smaller Alto does much worse. If the average on flat terrain is really under 500 - that's better than the 22' Sport Airstream and only slightly worse than what was listed for the Bowlus.
The Airstream has a full bathroom with a separate shower - which is a plus. Most of the smaller trailers have the combo toilet/shower (including the Bowlus).
We really like some of the features on the Limited Edition Bowlus - the ability to go off grid - even run the air conditioning for "up to 4 hours", plus the provided cellular booster and WiFi repeater/cellular/router. But those are features we could add to other trailers - and have been looking at upgrades to the Airstream to give us LiOn batteries to power the 110 outlets and solar for recharging without a generator. But even with those upgrades - the Airstream would be much less than even the entry Bowlus.
Going to look at an Airstream this weekend - hope to see a Bowlus next month - and will take a look at the 21xx Alto trailers...
