I camped in tents with my family since birth (1961). I also tent camped as a Boy Scout for many years. As a teen my parents bought a Nimrod PU that had nothing but beds (no sink, heater, water, etc).
When I got married, my in-laws had a TT so we stayed with them. When we had our first child, we tried to tent camp, but it became too difficult, so in 1991 we bought our first PU, which was a Coleman with a sink and stove. Over the next 10 years we upgraded twice to PUs with more options, such as a heater and shower.
In 2006 we bought our first TT, a 24' with no slides. Last summer we upgraded to a 28' TT with a slide out.
We've owned 5 different RVs over the last 22 years, after tent camping for decades. So I guess you could call us "old-timers".
