You have some nice options narrowed down. My question is what kind of pickup are you pulling this thing with? Sure there are pros/cons to buying new vs used. But if you are like me, I didn't want to sleep in somebody else's trailer.
However, your towing vehicle is the most important factor to what you get in my opinion. I bought a camper that pushed the envelope on my TV, and paid for it with a new transmission when I forgot to put it in tow/haul mode. My fault, costly mistake. My new truck has a much higher towing cap so it is a lot more comfortable to pull.
All that said, I looked at that catalina and loved it. I really wanted it, and still regret not buying it. Of course, it's a lot heavier than mine so there was no way in hell I could've gotten it without getting a new truck
