ALS Diesel

ALS Diesel is a truck and diesel repair shop based in Janesville, Wisconsin, right off I-39/90, U.S. Highway 51, WI 26 and U.S. Highway 14. You can bring the rig to its shop, and it also runs 24 hour mobile roadside service, so a breakdown on the highway does not always mean a tow.

It lists motorhome maintenance and repair and trailer repair and maintenance among its services, alongside electrical systems, batteries, air conditioning, brakes, engine repair, heating systems, starting and charging, suspension and transmissions. It works on CAT, Cummins, Detroit Diesel, Duramax, Isuzu and Power Stroke engines, and serves motorhomes and trailers. That engine list matters if your rig is built on one of those diesel chassis, since a shop that lives in Cummins and Detroit Diesel diagnostics day to day is not learning your powertrain on your dime.

No trip fee, hourly rate or diagnostic fee is published, so ask about the trip fee when you call, along with whether the mobile service reaches your location. Shop hours run Monday through Friday, 7am to 5pm, with 24 hour roadside assistance on top of that for emergencies.

ALS Diesel has been in the repair business for more than 20 years, with experience across light, medium and heavy duty trucks, trailers and cars, and says it specializes in diagnostics and electrical repair. Google rates it 4.7 stars from 15 reviews.

This is a good fit for an owner near Janesville with a diesel motorhome who wants a shop that already knows CAT, Cummins or Duramax engines, or a traveler broken down along I-39/90 who needs mobile help without waiting on a tow.
