If your motorhome GVW is under 18,000 lbs, it's classed as Group 1 Light Vehicle and can be inspected by any inspector that's Group 1 qualified (most are). The inspection facility must have a bay large enough to bring the vehicle inside though, they are no longer permitted to do inspections outside for some reason. Group 1 vehicle owners over 10,000 lbs can also request a "Heavy" Group 2 inspection instead of a Group 1, in which case the inspector must be Group 2 qualified of course.
