The Signature Scoreboard
The Miller Index
Every modification on the Astro, scored across five categories that actually matter in the backcountry. Scores are honest — and honest includes Not yet rated when we don't have the miles to back a number up.
Reliability
Does it work when we need it to, every time?
Comfort
Does it make life in the van better?
Capability
Does it change where the van can go?
Maintainability
Can we fix or service it on the road?
Value
Was it worth what we paid for it?
Scores can change. A newly installed part with a 4 today may earn a 5 after a hard summer — or lose a point after a hard winter. We update the index as evidence changes.
