Help me decide my next camper

I'm looking for some thoughts/suggestions. I have a 7X16 conversion that has worked well for long trips when the entire family goes camping. We are a family of 6, mom, dad, and 4 kids ages 9 to 1. I expect to get lots of years building great memories with it. I don't like towing it for one or two nights when it is just me and one or two kids going for a couple nights. Would also be nice to have something our 12 year old minivan V6 Town and Country can tow into the mountains when we go to KY to visit family and camp on the old family farm. One of the main concerns is weight and then cost (within reason).
My number one choice is a used 2017 Intech Flyer XLT asking $7,500. I called and it is called the Chase now. This one has AL frame and outside skin, roof rack, electrical already installed, and Coleman rooftop AC. It appears to be ready to go.
Or we could do another cargo conversion:
New Patriot cargo trailer from Trailers Plus 5X8 for about $1,900 - rear ramp and side door
Used Continental Cargo 5X8 built in 2000 for $1,400 - rear ramp and side door - about a 3 hour one way drive
Used Haulmark 2006 for $1,100 Barn door on the back. I'd rather have a ramp for a deck, but I can make it work
I thought about building a camper from the ground up, but I'd rather be camping with the family than building something that probably would not hold up as well as the trailers above. I tried / replaced the roof on our Coleman Popup camper - built it way too heavy, within a couple years the new roof had water damage, and the canvas and inside was already really rough. So, anyone interested in a popup camper frame? Still has the floor, lift, and part of the sides...….. I'll probably put it on Craigslist in a couple days. I'm in Wilson NC. On a side not, how much should I ask for the frame and tires?
