We started camping in tents in our mid 30's when we became a couple. After several years we started renting cabins and cottages. At his age 60 and me 55 we purchased our first motorhome. A 36' with 2 slides. That is what we fulltime in now and it will be 2 years in May. It was 10 years old when purchased- we'll probably keep it for another 5 years before replacing - maybe. If everything is still in great shape we may keep it longer - who knows.
