Okay, I love talking about my FC so you don't need to ask twice!
We bought a 1998 Pennine Sterling about 5 years ago, just to see if we liked the FC (we had tents before that). Fell in love with it, then just before the pandemic we replaced it with a newer Pennine Pathfinder as I fancied the mod cons such as an onboard toilet.
Absolutely love the folding camper. All the advantages of a tent (the lovely evocative zip noises, the sound of rain on the canvas, that 'fresh' smell in the morning) but the luxury of a caravan (beds, sofas, hot and cold running water, fridge, hob and oven, toilet and sink!).
I'm not as experienced with caravans I'm afraid but when I looked at them I couldn't see any that had two double beds permanently fixed. If anyone wants a nap during the day they can, without disrupting the seating areas. We make the sofa into a third double if needed, so the camper takes a family of five (including three teenagers) with ease. Our awning is the same size as the camper itself so when we put it up it doubles our available living room, but the added advantage over a caravan is that the front canvas 'wall' of the camper body zips down, so you effectively can make one big room of the camper and the awning by doing so - feels VERY roomy and decadent.
We keep ours in our garage, we wouldn't be able to store a caravan at home. As a pp said, quite easy to push around manually but I might get a motor mover at some point. Towing is a breeze but I've never towed a caravan so I can't compare. And I've never taken it to the continent but lots of people do (and I plan to, one day) and I understand the ferry charges are cheaper than a caravan....?
Totally recommend it. 100%. You could always do what I did - buy an old battered one (although it was totally serviceable and is still going strong today, I gave it to a family member!) to see if you like it first.
