We started RVing in 1990 with a 1979 Jayco Cardinal tandem-axle pop-up. That old tank was the largest pop-up Jayco built and slept 8 people!! The roof and canvas had just been replaced by the Amish (we lived in Ohio at the time), and we picked it up for $2,500. We camped in it 6 years, and all I ever had to replace was 1 tire that threw a tread on a summertime trip across Texas - we pulled that thing from Lake Erie to the Rio Grande several times. When we moved on to a 5th wheel in 1996, we sold the Jayco pop-up for $2,450.
Total cost of ownership - $50 and 1 tire. :-laf
We still talk about the trips we made in that Jayco. As far as I know, the young couple we sold it to may still be using it.
