FAQs
Can you service trucks at a Downers Grove corporate campus or office park lot?
Yes. We service trucks wherever they’re parked, as long as our technicians have authorized access to the property under your Master Service Agreement.
Can you provide procurement documentation for our Downers Grove office?
Yes. We provide a Master Service Agreement, proof of $2,000,000 liability coverage and Net-30 terms once a business credit application is approved.
Do you service medium-duty trucks in Downers Grove?
Yes. Medium-duty trucks run on the same program as Class 6-8 tractors and trailers, so your whole fleet is on one schedule.

Every finding is documented with photos and video in your Fleet Portal before you approve the work. Retainer accounts have pre-authorized repair limits set at enrollment, and anything above that limit needs your digital approval.
