I understand how you feel, although our situation was a little different, as we had to sell our beloved VW camper that we'd had for 10 years (and was the fifth one we'd had) last year and the thought of getting a caravan instead wasn't exactly inspiring.
I have to say though, I have been pleasantly surprised. We bought a vintage caravan (1979, same age as our last VW) last Autumn and dry stored it over the winter, before doing a few little jobs on it in the Spring. We had our first trip away in it in May, 4 nights/5 days at a music festival and I was totally sold on it by the end. So much easier and more comfortable than the VW or a tent and a lot more private too.
It's not all mod-cons, as we like to keep things simple. We have a water pump, but only cool water. There's a portaloo and bathroom sink but no shower. Kitchen-wise there's no oven (although we could fit one, as it was an option when the caravan was new and the space and fittings are there), but we do have a decent double burner cooker and grill, plenty of work-surface, a proper sink that we can actually wash up in, with a full-sized draining board and for me the fridge was a massive bonus, having previously only had coolboxes in the VW.
I'd agree with Viva. Being a vintage van, it's lightweight and we can therefore leave most of our kit in there for towing without exceeding the payload/weight-limit. All we need to do is sling our bags of clothes and the kids clutter in the car and we're off, which is a massive bonus when you have two big dogs taking up all the boot space like we do.
I am a total convert, having been adamantly against the idea this time last year. Nothing at all to do with all the fun I had sourcing original 70s pans/crockery and other bits to dress the van with.
