We got the same deal as Tom and I questioned the guy. First, we had to bring the motor home to them so they could lay eyes on it (yes, our registration says motor home). We parked it on the street in front of the test station so we didn't have to struggle to get around their tight turn lanes. They looked out the window, said, yep - testing waived. Second, he said part of it has to do with length and how it works with their current system so if we had a shorter rig, we might have to go through emissions tests even with the motor home (which is probably another reason they have to lay eyes on it). Third, he said laws change all the time so we may need to get tested in the future. I guess the test may change also. I wouldn't be surprised if future tests were as easy as walking up to a vehicle with a tablet computer and a plug to access the vehicle computer... which brings us back to the recall and them "fixing" their emissions data.
