I was 30.
We were expecting our 2nd child and needed to upgrade to a larger tent or... we ended up getting a Scamper pop-up trailer. I wish I had logged officially how many miles we pulled the Scamper. It went throughout the Rockies, the East coast, and across Canada. Some of our best family memories happened with that little RV for the 18 years we had it.
Once our last daughter was in college we went from the pop-up to a hybrid TT. When she graduated we went to a TT, eventually to a 5W, and then last year to the 5W we now have. Our two kids have long since been grown up and how have their own pop-up and a TT, and are creating their own memories for their families.
