There is another way to go and that is with a Harbor Freight 3/4 ton trailer kit with the 5 lug 12 inch wheels. These wheels are taller and allow for faster towing speeds. The kit weighs around 275 pounds. You add 3/4 plywood to that and you are at around 425lbs. I built one with all kinds of plywood once to clear out a storage unit and later use it as a storage container in my driveway. I towed it with a Toyota Yaris. Now that's just about as minimal as you can go for a tow vehicle. You can get those trailers on sale at a percentage off sometimes.
Anyway my first attempt went way overboard from my original idea. You build the trailer to work as the floor of your tent. It has two foot sides all around the edges and they all fold down and are supported as wings of the tent. So you end up with a flat surface of 8ft by 8ft with a 2ft by 4ft extended alcove on front and back when they are all extended. You just come up with a way to support these fold down sides. All your camping gear goes inside. You fold the sides up and the tent that is already inside covers all your camping gear and is already permanently attached to the floor. So it goes down the road as a 4ft by 8ft trailer. You always have a water proof flat floor about 14 inches above the ground and you can level it perfect with your adjusters. I found junk yard scissor jacks for light cars for $10 each and used them to level the main trailer. They are bolted to the bottom of the 4ft by 8ft HF frame.
You can see by the picture that I did not build the original idea. The side walls are suspended by an elaborate 2 by 6 floor joist system that was way overkill. I then made rounded rafters that fit on to the raised walls when it was set up. This was a very time consuming effort each time I set up or tore down. Anyway. You can hall all your stuff, or more stuff, with a trailer and a flat platform that folds down into a perfectly flat floor for each campsite. It all comes down to your idea to support the fold down wings. You don't even need to build your own tent. You can set up any commercially constructed tent that will fit on your fold down platform. I know how to work with vinyl coated polyester so I went that way. There is a way to make this a perfect square too. It would be 8ft by 12ft if you can figure out the fold out supporting system. That's huge. If someone figured out a pole system and roof rafters then it would be awesome. There is no reason this could not be a single high pole in the middle. It would always be staked down to the fold down wings. You could just open one of the doors and go inside with the single fixed height pole.
Here is a picture of the first build. I lived in this for 2.5 years and put it up and down every three weeks.

I like this idea. Someone camped near me at Qsite had a similar set up. They also put up a canopy for their kitchen area, which was pretty elaborate, they had about 3 kitchen boxes and a couple of tables. I really do like a kitchen area outside of my van.
Came the winds, as they always do in Qsite. The trailer mounted tent did just fine. The canopy, not so much. When they left, the tent of course came down and was folded up into the trailer. Kitchen stuff packed in on top of the tent. Pulled it with a mini-van.
If I could stand to tow, I would seriously look into a similar set-up. But I'd use a much sturdier canopy!
