We debated this for a few years and ended up in a used Class A rv. Seems like everybody we talked to that had a pop-up hated it or wanted to upgrade. We looked at travel trailers, but my 1/2 ton SUV is (14) years old and anything over 25' probably would have pushed it, wasn't looking for a new truck and I don't like towing a long trialer from the reece hitch. Next choice would have been a fifth wheel, but would have required a new truck, maybe we'll go that route in a few years.
We looked at several used Class A's and found the perfect one off season. The kids love it, lots of room and easy to setup once you get to the campground. Easy to pull something behind as well (tow car, golf cart). Fun to drive too....you can find them about (10) years old with a slide for around $20k and under, most of them with the Ford V10's. Class C's are nice too. As stated before, check the roof & tires. Good luck!
