John's Truck Service Inc. is a diesel truck shop based in Tucumcari, New Mexico, at 6297 Quay Rd. It is a fixed shop, so you bring the truck or RV in. The shop asks drivers to "Bring it on in to our shop" for engine repair.
The shop works on diesel engines from Cummins, CAT and Detroit Diesel. Its work covers computer diagnostics, emissions testing, and preventative maintenance such as changing filters and tightening belts. Repairs run from misfires and loose throttle linkages to driveline problems, no-starts and sensor malfunctions. It also sells Cummins parts. The shop describes its work as "engine repair for your truck or RV," but it names no RV types and no RV-specific services, so ask before you bring in a motorhome or trailer. It serves Tucumcari, Santa Rosa, San Jon, Newkirk, Quay County and Dalhart, Texas, along with the surrounding area.
No hourly rate, trip fee or job prices are published, so ask about the rate and any fee when you call (575) 461-2085. The shop offers "a free estimate on services." Hours are Monday through Friday, 8:00 AM to 5:00 PM, and the shop is closed on Saturday and Sunday. No after-hours or emergency service is stated, so ask before a weekend breakdown.
The shop calls itself a "full-service Cummins, CAT and Detroit Diesel Dealer" and lists "more than 4 decades of hands-on experience," dating to 1976. A dealer for a brand generally has factory training on that brand's engines, so ask who will work on your engine. No technician is named, and no warranty, licensing or insurance is stated, so ask about those before the truck comes in. Google rates the shop 4.6 stars from 135 reviews and lists it as an RV repair shop.
This is a good fit for a diesel truck owner around Tucumcari and Quay County who wants engine diagnostics and Cummins parts, or an RV owner who is ready to ask first whether the work covers a motorhome or trailer.
