I have a recommendation for any RV'ers visiting Livingston who need to get their inspection done. This place will inspect vehicles, motorhomes, towed trailers, and fifth wheels. There is ample room in front of their shop to maneuver your rig (unlike a couple of the other local inspection places).
The fellow who did my inspection was knowledgable about travelers who may be showing up to get their inspection done well after they got their registration (unlike another place that told me I didn't have to get inspected at all).
Soda's Auto Repair
6709 Highway 190
If you are coming from Livingston, head east on 190. Soda's is 6.2 miles after the intersection of 190 and 146. It will be on your left as you near the top of a hill and is across from a cell tower.
