Last fall, we sold our pop up camper after Syd's elk hunt. We'd outgrown it. We shopped and shopped around and finally decided on a 2018 Springdale bumper pull 24 footer. You really have to go look at the layout and what you ultimately want out of it. Ours has an indoor kitchen, but the dining area is the slide out. Two bunks in the back, next to the bathroom and the master bed up front, with accordion doors for "privacy" (yeah, right). Like others have said, if you go used, inspect the hell out of it for trouble spots. The biggest thing my kids hate is that I am dragging my feet on getting the septic system up and running. Where we camp, there are no black-water dump stations and dumping your black (even grey) water in the National Forest is illegal. I've seen a couple of spots where folks did it and its gross (beyond gross). Most of those developed campgrounds have a dump station, so you should be set there!
I have a friend out here who splurged on a Lance a couple of years ago and its been nothing but trouble for him. I've heard that from a couple of others, too.
