Though we are full time rvers today, traveling in a large and old Fleetwood Bounder, we still had small rvs in our lives when he had to work the old 9 to 5 life. For us, it was an escape on the weekends, an inexpensive way to travel on our budget....right outside of our front door.
Our first inexpensive recreational vehicle was a pop up camper. Though I can't remember the length now, it was bigger than most on the road. It was old and cheap, and we actually took it from central Illinois all the way to Glacier Park, Montana! Many weekends we would take it to our favorite camping spot, 70 miles away.
A pop up camper can be a lot of fun - a cross between tent camping due to the canvas over the bed, yet easily portable (we kept our gear inside so we could leave anytime) and accessible when you just have to get out of town for a night. However, there are many pros and cons you should be aware of before buying a popup.
