I think Kuzbro hit it. Not only do the bean counters track every piece of material, but also labor. Everyone on a production line is required to keep up, regardless. The worker who regularly halts the line to fix a minor issue just isn't going to last long. Also, they are required to produce X number of units a day, so it's easier to let the dealers correct warranty issues and make production quotas. That is why all of my repairs and mods except one have been done by me. I put out a better quality job that the dealers and certainly better than the factory. Thats just a way of life in a production facility.

I now have a Keystone Outback, but I try to help when I can.
