Vail has about 5,339 households and a median household income of $121,385 - noticeably higher than the wider service area's $90,758, and it shows in the kind of doors and openers installed here: more insulated steel doors, more openers with battery backup and smart-home tie-ins. Compare that to the broader area, where 65,148 owner-occupied houses span a build range from 1980 to 2007 across housing stock that's mostly 1980s and 90s vintage - Vail sits at the newer edge of that range rather than the middle. That difference is why we don't treat this as a generic Tucson-area stop. A door installed in 2007 has a different failure pattern than one from 1985, and we plan the parts we bring accordingly.
