If your diesel motorhome is covered by CARB’s Clean Truck Check, you do not have to drive it to a test station. We come to your home or storage lot and run the OBD test there.
Not every motorhome does. CARB says the requirements apply if your motorhome is non-gasoline, has a manufacturer’s GVWR over 14,000 lbs, and is registered in California. The GVWR is usually on the label at the door jamb. Gasoline motorhomes and lighter vehicles are generally not covered.
Not sure? Check CARB’s motorhome page or call or text us with the year, make, and GVWR and we will point you in the right direction.
According to CARB, covered motorhomes must be reported in the Clean Truck Check Vehicle Inspection System (CTC-VIS), have the annual compliance fee paid in CTC-VIS, and pass annual testing by a credentialed tester. CARB links compliance to DMV registration, so falling behind can lead to a registration hold.

We come to you, connect our testing equipment to the vehicle’s diagnostic port, and run the OBD-based test. Hands-on time is typically about 15–20 minutes. We submit the results to CARB and explain what is left on your end. Official compliance is recorded by CARB, not by the test alone.
A large motorhome is a hassle to drive and park at a test station. Testing where it sits saves the trip, the fuel, and the parking. We need to reach the vehicle and its diagnostic port, and you should check HOA or storage-lot rules about visitors first.
No additional travel charge in Temecula or Murrieta. CARB’s compliance fees are separate. Book on our Square page, or call or text (951) 395-1018.
If several eligible diesel motorhomes are in the same storage lot or yard, call or text and we will coordinate a time together. Additional vehicles are quoted individually.
We test eligible vehicles with 2013 or newer engines by OBD. We do not offer opacity (smoke) testing, so vehicles with older engines may need testing elsewhere.
