My first caravan was a freedom sunseeker. 10' long and 4 berth. Very basic, sink with electric pump cold tap and built in fridge. 2 ring hob & grill. Very solidly built in fibreglass using an alko chassis. 4 seat dinnette plus 2 seast dinnette and a wardrobe. Loads of roof lockers plus undereat storage. Mains & 12V electrics. Had an awning longer than the caravan. No heater or toilet.
It did work very well but was small for the 4 of us plus dog but we did get by in it. I did like it very much. Towed it with a mini metro. The microlite is smaller and only a little lighter. Still 750kg max.
Our Dandy designer is bigger inside once up, much easier to tow with a small car, uses less fuel, but has less storage and no fridge. I think a high side destiny would certainly be much roomier and still easier to tow.
Oddly, the method of use is different between the dandy and caravan. With the caravan, everything is carried out and put in its final place in the vsrious cupboards and lockers, fridge etc; then carried back into the house at the end of the trip. With the dandy, everything camping orientated stays in the dandy and everything like food, clothing etc stays in the car. This makes packing & unpacking much easier.
