They are great if you don't mind not having a bathroom and can deal with a little noise. They are a HUGE upgrade from sleeping on the ground, offer plenty of comforts with a bed, AC/heat, kitchen, etc. I grew up in a pop-up camper and loved it. We have 3 yappy dogs now, so we needed a hard sided trailer to keep them from hearing every passing noise and ferociously yapping at it. Pop-ups take a little more work though. They aren't as easy to set up, take more time to tear down. If it rains while you are camping, you gotta open it up and let it dry our thoroughly when you get home.
Check the tires on each trailer. Most trailer tires are rated to 65. I have a 2015 Jayco that has tires speed rated to 75. Pop-ups tow so much more easily than a 5er or travel trailer though. Your fuel mileage will be substantially better.
The price depends on the brand, model, features and condition. A nice condition 2006 with a water heater, fridge, newer tires, etc could easily be worth $7500. Then again, it it is dirty or stained, has rips or tears, older tires, no water heater, broken AC, etc then its worth closer to $1500 in my mind.
Good luck though. Our family LOVES camping. We've been camping as a family since 2005, on our second camper now. So far this year, we've been Florida/Charleston/Savannah, to the lake twice so far, have 2 trips planned to the ocean, another trip planned to the lake, going to Amish country in PA, Gettysburg PA, hoping to get to NYC later this fall and probably a couple other trips in between. Its a great escape, especially if you own the camper. You've already made the big investment in those vacations... all you gotta do now is use it! The more you go, the cheaper each trip costs!!!
