I was wondering that too. I know there were only 22 195SR's built, but I have no idea on the number of Que's. It sure seems like there's a lot out there.
Could you PM me with your VIN, or at least the last 4 digits? That is the production number. I'll compare it with other pictures I have of Sunline's and VIN's from them (from eBay, etc) to see how high it really is. That number will only tell how late in the production year it was built. It has no relation to the total number of Que's. Also, could you look up the build date, found on the side of the trailer or in the owners book?
