Where we live all large trucks over 6600lbs must be inspected annually to get plates. This is a commercial vehicle inspection and normally takes 1 to 1.5 hrs, fixed price $179.00 and if you have to come back because they found something $29.00. All my MVs go through the inspection. We have a M35, M109, the MV toy hauler, soon an M816 and M1010. The biggest problem is when you bring the truck in and they stand around looking at it trying to decide where to start. Thay are use to commercial vehicles not MVs, our biggest problem is clearance lights and the lack of on MVs, we have had to install a whole bunch of lights to conform. Now brings on the next issue is the truck registered historical, that changes the inspection rules.
