the 10 year rule, how common is it and how is it enforced

Our 2003 Jayco Jay Flight 5er was an insurance company paid for replacement for our 2002 Jayco TT RV which was totaled in a rollover accident. "JJ" is now 10 years old and aluminum "stick and tin" construction, still looks brand new and we have never even been questioned about how old it is..always welcomed in any RV Campground we've visited in the past 10 years.

As long as an RV doesn't look like a rolling pile of junk that th Beverly Hillbillies would be proud of...you should be welcomed with open arms!!
