FAQs

Our service area extends 60 miles, reaching communities like Converse, Schertz, Universal City, Austin, Selma, La Vernia, and New Braunfels, TX.

How Often Should I Schedule Preventive Maintenance for My Truck?

Preventive maintenance should generally be performed every 15,000–25,000 miles, depending on your routes, load type, and driving conditions. For trucks operating in demanding environments like San Antonio’s urban traffic or high-heat conditions, more frequent inspections can prevent early wear. Consistent maintenance helps extend your engine’s life and reduces costly breakdowns.

What Are Signs That My Trailer Needs Repair?

Common signs include uneven tire wear, reduced braking efficiency, air leaks, or flickering trailer lights. If your trailer sways or feels unstable, that’s another clear indicator something’s off with the suspension or axles. Addressing issues early ensures compliance with DOT standards and helps avoid dangerous roadside failures.
