The search can be discouraging, that's for sure. So thanks for the encouragement and for the links. I have been looking at craigslist and I was aware of rvonline -- I'll have to look at it again. You speak the truth about the tires. I've seen just one dealer take a photo of the date stamp on the tire, everyone else just advertises them as "great tread." And I've had enough blow-outs (even on new OEM tires), and seen enough scallop marks on the highway leading to wrecked cars that I don't play the old/used tire game -- not if at all possible. It's not worth the risk and/or the insurance claim.
