RVs over 10 years old are valueless

DH and I have a 2006 Class A - we keep it in very presentable condition - would NEVER claim it wasn't over 10 years old - can tell simply by its design! Don't think a Georgie Boy Pursuit has been produced since maybe 2008? Anyway. Most of the CGs we have come across with a "10 year" rule have been priced beyond our willingness to pay! We like the "bells and whistles" of a "Resort", but can easily do without. No point or reason to argue - we just go somewhere else! Love state parks when a site is available, but also very willing to use a privately owned park. One thing we have learned inover 45 years of RVing - flexibility is the key!
