Sun Lakes runs about 8,650 households, small enough that the truck isn't guessing what it'll find at the curb. Most of the houses here went up around 1990, which puts them in the same build window as a lot of the broader Gilbert service area (median year built 1993 across the region). That means torsion springs sized for late-80s/early-90s door weights, steel openers from the same era with worn drive gears, and galvanized track that's been baking in the sun for three decades. The truck carries springs in the wind sizes those doors actually take, standard-drive opener gear kits, and roller/hinge hardware sized to fit doors from that build era - not the newer thinner-gauge panels going into houses built in the last ten years elsewhere in the service area. If a part on the truck doesn't match what's on the wall, that's a second trip, and we'd rather know before we drive the 10 miles out.
